Wow, art direction and general quality is really really good and I could imagine buying a fleshed out version.
My only negative so far is that invincibility feels like health or run time. But I know I struggled with the theme as well so that´s fine for me ;)

The quality of this game is through the roof, especially considering it was made in only 15 days! The only complaints I have are all so minor they didn't really affect my experience that much:

• There didn't seem to be any difference between the enemies. Not that it was a problem. The skill tree had all my attention absorbed, so I wasn't really thinking about it.
• Perhaps a slightly faster way to collect coins in the larger combat rooms? Or maybe I'm just too trigger-happy.
• In the larger combat rooms, occasionally enemy billboards would z-fight with each other.
• Invincibility felt more like health. And while everything was polished and balanced to the T, none of the mechanics particularly stood out as revolutionary. At the same time, "Invincible" is a difficult theme to deal with.
• While I could definitely see how some would enjoy searching for the corridor coins, it slowed down gameplay, which made it a bit fatiguing for me in particular. At first, I felt obliged to collect them all to optimize efficiency, but after a while, I ignored them so I could go through the runs faster. In contrast, I loved the weakness exploit ability. It added a thrill to combat.
• Eventually I got to the point where I could one-shot most enemies, so I didn't feel any need to upgrade my sword, which led me to ignoring crystals all together. Instead, I would try to upgrade chain lightning so I could take out multiple enemies with one hit.

I'm only writing the negative things, because if I wrote down the positive things, this comment would be way too long.

Excellent game! (and I'm not just saying that :D)

REALLY AMAZING GAME, I LOVE IT! Also i got motivation to do something like that, i really like this sort of games :>

Excellent game the art is really good.

Damn what an excellent job! One of my favorites so far. The game loop is fun, the art is consistent and the game is very well polished. The only minor criticism I have is the game starts a little slow for a game jam game, but it is a lot of fun when you start getting more upgrades.  

I eyed on your game for some times before trying it and i was not disappointed. The artstyle is really pretty, the game is well balanced (for the upgrade system), the audio set us in the good ambiance. It was a joy to play this game. 

I really hope to see a release on day ! In the meantime here's some things that, i think, could be fun to have :
- relics in the chest to have some more effects on the enemies or on ourselves
- The player could move a little faster, even if it's fun, as we loop, it's kinda annoying to move slowly (even if it's useful to catch the little coins hidden) 

Anyway, i love the slime and i'm curious to see how you'll polish your game !

Really pretty and polished! Like it's been mentioned by others, I wish walking/progress was faster. 

Great job!

This one might be my favorite in the jam!

 It feels like a full polished game, rather than a prototype. The visuals are super atmospheric, and the 2.5D look is a really creative approach. The gameplay is simple but very fun and addictive.

 I really hope you keep working on this!

I'm still playing it as I type this but wow, what a great game. Super polished, and a great idea. I agree with some people that the walk speed could be a bit faster, but it did also help me realise that walking gets rid of my invincibility, and would likely be harder to get that if I was sprinting everywhere. Amazing job. 

dawg, switch to godot, we need a collab

I like it but I wish the player moved faster. Basically my singular complaint.

Aesthetically its great, gameplay wise one of the best from the jam by far. 

Amazing art style and you really nailed the vibe! :)
You have a really good foundation here, the only small thing is maybe that there would be great with more involvement / stakes in the different "rooms" so the choice of path feels more impactful! 
But overall a really good game!

I loved the art, the 2.5d feel and the upgrades! amazing work!

The only things i would like to see is a sprint button and maybe a more action packed or strategic way of combat (maybe thats just me) those things would problably have kept me engaged for longer personally!

This game is really polished as a whole! The art, audio, and everything altogether is pretty great! One problem I had was the lack of involvement in the gameplay loop at first, but that was fixed with certain upgrades. My biggest complaint was the movement, because the player is so slow and I didn't even realize there were movement upgrades for a while because of how late they are. Overall, still a fun game with a neat gameplay loop!

This game is straight fire dude. Idk how u got so much done, but its fun, pretty and really solid implementation of the theme.

Very impressive! I got to the 12th room or so; I spent a lot of time playing  this. The gameplay loop is addicting and I think your game is a strong contender for an award. Beyond that, I think this would be a great game to continue working on past the jam.

A couple ideas I had:

- I think the lockpicking minigame could have more risk/reward. Maybe a time limit or dynamic rewards based on how fast you unlock the chest? Also a few of the route choices you get are strictly chest paths which I didn't really like (one instance I got the choice of 3 identical chest paths), I feel there should always be a fight path option.

- A few others also had this complaint; the base speed is pretty slow. I think speed upgrades should come earlier instead instead of having the feature of skipping ahead. If speed is important, some of the hallways could vary in distance (perhaps to a stronger elite enemy with better loot).

- A one-time use item shop would suit this game well (or as rewards in the chests you're trying to unlock)

- I think the game would benefit from some enemies that attack the player; this would prompt the user to strategize which enemies to hit first.

Addictive. This game is absolutely amazing—the work you’ve put into it is incredible. There are so many great features, and I highly recommend you keep working on it!

Regarding feedback: I’d like to have a real choice in the path: sometimes I could only choose one sign, making it an obvious choice. Chests are always more important than mining, which seems clear from one perspective: they give you more free stuff, but it’s also true that after opening two, I was set for two sword upgrades, making the mines practically useless.

As a Incremental lover I really loved the idea ! There can be sprint or something maybe because every time walk slowly like that really bored me except of that sometimes when i rush clicked i selected that path i dont want it maybe it can be prevented somehow. 

Visuals are really exceptional i really like the style and presentation. Congrats !
