Fun: At first I was going to say the game felt a little simple but was still fun, but then you added the console which added more to the gameplay. Then I was going to say that players could make the levels boring for themselves by moving super slow, but then you added the oxygen mechanic. So now that I don't have any notes here I'll just say for a game jam it's probably better to have fewer levels before you introduce mechanics because a lot of times people will play only the first few levels and rate based on that and for me it felt like the levels were getting a little old before you added the console. The other thing I will say is that the character rotate made the movement a little hard to know which buttons to press to go in but I don't really know how you'd fix that, maybe have the keys next to the player showing what buttons go in each direction? Anyways I had a great time with this on!
Presentation: This pixel art in this game was super impressive. I'm not much of an artist myself but I do have a few pieces of advice. One thing that I noticed was that the art felt a little flat and a bit more shading could've helped. I also have used a vignette around the screen to help and make the game look a little nicer. The main thing I felt this game was missing was some background music but the atmospheric noises do help with that a little. Loved the starry background particles as well.
Creativity: Not a crazy idea but an interesting take on the theme and the ways you were able to expand on it worked well! Good job here.
Overall: Wow this game was really great! I kept getting surprised at how much you guys were able to add in and how polished it all felt. Keep it up.
