I really liked the aesthetic! Both it and the overall design reminded me of the original Metroid 2 for Gameboy.
I think the physics of the jump could be a little frustrating since walls could seemingly stop horizontal momentum, making it difficult to jump up when next to them. It did add a little bit of difficulty to it though, which was fairly interesting to work around.
Also, I think the text tracking actions in the UI was quite nice. Really solid work considering the brief amount of time it was made in.
