Nice platformer! I included it in my compilation video series of all of the GBJam 5 games, if you'd like to take a look :)

Nice game. It's good to bounce enemy bullets back at them :)

I felt the movement a bit weird, maybe something to do with the high gravity and the horizontal acceleration.

A cute little platformer! Although the character's movement felt a little bit strange to me (the double jump needs a really quick double tap to gain the necessary extra height), the reflect mechanic was simple but worked well. While I needed a hit or two to figure out how the health meter worked, I found it very fitting with the bubble-themed power-up.

The jump is difficult to master. Cute little penguin character!

This game is very nice.

The controls are a little weird for me (I would prefer to move using the arrows), but the game is great.

Good job!

Cool platformer, but I feel like the gravity is too high for it.

This is a really nice game, possibly my favourite so far. I'm surprised it hasn't had more ratings. You might draw more attention with a gif for a main screenshot - take a look at gifcam.

I found the jumping quite difficult at first, but once you get the bubble and double jump it gets a bit easier. I very much like the health indicator design, when you get hit, no clutter. The music and SFX are good. Great atmosphere for a little game. It all fits together so well.
