Made it to wave 25! It's a surprisingly well-balanced experience, with an equally surprising amount of depth to the upgrade choices and possible builds. I would have liked the early game to have some more variety, maybe starting with some money or having cheaper starting upgrades so you can get started on upgrading right away rather than after room 3 or so. 

I also noticed a few of minor issues, nothing that hindered gameplay though. Those issues were:
1. Sometimes the bone-chuckers would just not chuck bones? Seemed to be in certain rooms, I think pretty consistently in the top left room they would just kinda walk around.

2. The center room seemed to not have a shop? Made me think it was a chance thing for each room to have a shop but no, that seems to be the only one without it.

3. The wall at the bottom of each room, while looking cool and adding some legitimacy to the space, would often cover up enemies. I found myself walking into that blocked area sometimes and would run into an unseen enemy, which didn't feel great. You may make the perspective sort of even more top down, like The Binding of Isaac.

Ultimately, I really enjoyed this game! I could see this expanded with more weapon upgrades, enemy varieties, and perhaps a more involved story or some kind of end game.

This game is great!! Feels like "Into the Gungeon" and "Binding of Isaac" had a Godot baby. Such a well made game and if you guys go further into making this an actual game, I'd definitely buy it!

Some feedback:
The bottom wall blocking the player was very annoying, lost a lot of my health due to not being able to see the enemy
Wish you could've had multiple upgrades and it gets very out of hand like Binding of Isaac
Ammo tracker could've been a bit nice, especially in the early stages
Player health not showing in shop, this would've been nice as there was times where I entered the shop, I didn't remember what my health was, so I wasn't sure if I should've bought a health potion and then left the shop. This then leads to my next point
Single access shop, because of my previous point, there was times where I just didn't get to buy anything cause I had to leave the shop to check my health
Not sure how the "it's broken" and "Through the teeth" were used in this game
Would've LOVED a boss fight after I had my 'build'

I felt like the shotgun muzzle was the strongest option, felt like I had way more projectiles and the range didn't really get hit that bad.

Overall, stunning game guys! Very well done!!

Really fun game. Probably the most fun one in the jam that I've played and/or seen. Love the SFX for shooting, the click when you're out of ammo, and the reload. The aiming and shooting feels super smooth, game has perfect performance, and just for extra completion points, there's basically a full options menu.  
The game is polished enough it feels like I'm playing a demo for a full product more than a jam entry.

This was really fun and well-polished, I think the overall flow is the best I encountered during this jam, it really got me into that endless just-one-more-round mood.

There are two suggestions for improvement I could recommend based on my experience:

• I didn't like the lower wall blocking my view, I ofted had to steer there and it was weird not seeing where I currently am (only based on the bullets when I still had some). At other times, the bone-throwing enemies hid there and didn't throw any bones, so it was a bit tedious to find them.
• This is just a personal preference, but I found it unfomfortable to reload with R, because I was using the same hand/fingers to move around. The right mouse button would be a great alternative.

Overall, very fun game, congratulations!

This was a lot of fun! Gets real challenging in the later waves. The reload animation was satisfying and I like the drawback of it taking longer with higher ammo capacity nice way to balance things. I do wish that the enemies had a brief window between when they spawn and can hurt the player. Found myself just running into an enemy that had just spawned in right in the direction I was moving when trying to avoid the ghosts.

One of my favorites so far! Your team did a great job!

Good game. I like the reload animation and the art style.

I normally don't like a lot of games of this genre though it took me playing for a lot! ahah great job!
Loved the art and the upgrades

This had the most fun game loop of any of the games I've played so far. I liked that you could build your own gun and make an overpowered automatic shotgun that fires rifle bullets. 

It would be nice if there was something to aim for once you've got all the upgrades you want, for example the shopkeeper could sell a key to escape the haunted mansion for 500 tears. 

The reloading animation is super satisfying and I really like how fast paced the game is. I really wish there was more depth (different enemies or one or two bosses) though. A bullet indicator would be very helpful. Great job game though!

Good RogueLike/dungeon crawler game. Upgrades are nice. Gameplay is satisfying. The only thing I would've liked is a bullet indicator.

Nice game! Reload animation is goated! The only thing i want is more! More upgrades, enemies, a story and some other weapons and you could have a game on your hands! (Just remember to keep it original!)

LOVED the death sound. <3
A very hard game - I wish I could tell what an upgrade would do before I bought it. I saved up for the rifle bullet (which kept getting more expensive for some reason), then when I bought it I found out it didn’t fly very far. I died just after. :/

Other than that, 10/10

Great job!  All the elements were really well done, esp that reload anim.  I would have loved gamepad support and some diversity in the rooms but it's a solid entry; I definitely should be in bed instead of playing more...
