I loved the animation for the shootings and the level design! Maybe you can try apprimorate the physics of the jump.
I had a great time exploring the map and solving the puzzles. Is a really nice and catchy game!
I remembered a video from GMTK where among other things he explores the dynamics of the jumps in relation to different characters and what itimplies in the feel of the game. Take a look after 3:11 on the https://www.youtube.com/watch?v=yorTG9at90g, it may be helpful eventually hehe (i know that for such a short period of time that the jam imposes it may be an overkill to take this kind of analysis over simple mechanics like the jump, but the video also brings a lot of info, so i think it's nice to share it anyway).
