I like the minimalistic style with character still having realistic animations. As an experience though I was quite lost. The blue orbs were unclear was I suppose to collect them or fight them. Attack also felt a bit un-responsive. I think there is a good base here for a cool exploration game, but needs some tweaks to the controls and more guidance for the player. Good job!

I was quite 'lost' from the get go. I believe that the game can do with some player-onboarding as not every player is going to read the description. The concept is interesting but I believe it could have been expressed more explicitly to the player through the game itself. 
The Shader on the player character is nice, having the whole world in that shader could be more appealing to the eyes (could just be me since I'm a sucker for toon/low-poly/stylized stuff 😅) The animations are smooth.
The implementation of the theme is a good out of the box take! 

great job!

I like the implementation of the theme! I just wish there were a bit more feedback indicators like when it's time to use the oxygen :) 

I liked how it tied into the theme. The hitboxes for some of the attacks felt a little loose, and occasionally if I attacked too fast I'd get stuck. The map felt like it needed a few more props in it to fill it out, but I liked the size. Good work!

Good implementation of the theme. The map feels a bit too big for the amount of things you need to find to survive. Also had bug where my oxygen showed full, then instantly dropped to zero and killed me. It would have also be nice to have a restart built in so I wouldn't have to refresh the page to play again. Other than that, nice work!
