Nice metroid-like presentation and vibes!

The concept is cool and the different power ups are nice, altought not very nice explained. With some feedback and improvements on the platforming side the game could be a very nice little metroidvania. 

Great gameplay concept and nice pixel art! 

Wow! Great metroid vibes!

Cool game for a jam. Well done!

This may sound immature, but it looked like the character became a fart rocket at some point xD. Well made game too! I agree that the level design needed some work

it's interesting how much stuff you managed to get into this small game. I do not like the controlls though for similar reasons as others have pointed out. I also think it doesn't fit the theme well enough, even after reading the explanation.

The presentation is great though, and making a small metroidvania in a gamejam is super cool. Good luck with the Jam!

My experience play by play with the game:

- Oh cool, it looks like Metroid Zero Mission, this looks competent.

- *Jumps* Oh, OK, the physics are Ghosts 'n' Goblins style where you can't change course mid-air.  That's more realistic I guess, but it makes these jumps harder.

- *Grabs power-up* Oh, neat, I can fly and shoot now, this is a really neat and cool power-up, I like this. *Dies by flying into beam grid*

- So then I decide to go left at the start and wind up flying straight up into the void.  Hmm, maybe I flew too high.  *Lands inside the wall*  Well, I guess true to Metroid, this has secret worlds.

- After falling in the water, I go right at the start now.  I collect a different power-up now, one that makes you invincible and/or invisible.  I proceed to get stuck between some pillars for a bit but make it out and head back left.

- Before finding a use for the invisibility power-up, I find one gives you the ability to shoot.  I run to the right firing liberally and then I Won?

Anyway, it looks great, and has a lot of mechanics, enemies, power-ups and everything, but the level design definitely needs a bit of work.

I liked the use of powerups, plus you made good use of the assets!

My biggest gripe were the collisions/physics not quite working as intended, with that fixed I think it's a really solid game.

I think this game has potential, though I think the controls hold it back a bit, mainly how you can't change your trajectory once you're in a jump so it's really easy to miss them. Presentation is very nice though

The graphics in this game are quite cool but sometimes there wasn't enough contrast between the background and the platforms. Nice animations! Hard to control the length of the jump. 

I think the power ups are cool and the checkpoint system is a big help. Controlling the player during jumps would be a great help.

Awesome presentation BTW.

Unfortunately, I couldn't enjoy the game that much. It seems very familiar to me. the movements are still very unclean. Even if you already use fully developed graphics. Nevertheless, for 2 days a good performance. 

At first I don't even understand how power-up work, I thought fly and fly + shoot is just different power-up, get invincible come back down to finish the game.
I just wonder how is this game relate to the theme, then I read the description... "oh so the power-up can combine!?",
go back to play the game again, get fly + invincible and explore everything lol.

(I see a lot of place that need fly + invincible to reach, most of them can even go out of bound ...)

Looks nice and Metroid retro, but held back by janky controls. Platformer would be hard in 48hrs. I was defeated by a slope so many times :P

This game reminded me of the Metroid.

Jump mechanic is really nice! looks interesting!

Nice concept!

This game is so stylish, i love it! controls are definitely retro though, the usefulness of flying overshadows the other powers.

Epic! Love the vibe and the power up idea is great. 

This game is really gorgeous, and I think the mechanic is a fun one. My main critique is that the movement is pretty tough, especially because there isn't any air control when jumping. Also, the powerups were kind of hard to differentiate, as well as determine their effects. Some text explaining what each powerup does, or some sort of compendium that fills in combinations as you learn them (or the player has to fill out) would be super helpful, and would fit with the theme of alchemy. Great Job!
