Not bad at all for a first game jam entry! Here are my complete feedback:
* Positive points
- The pixel art is pretty nice
- The universe used is quite rare in video games which is a good thing to see
----
* Negative points
- The music is pretty annoying
- No feedback sounds
- The movement system is a birt weird, it seems that the character moves by "square", so at the beginning I thought that I was stuck, but I understood that I need to hit the input movement each time for moving
=> Overall gg for your work!
