The core logic and mechanics are solid! I tested it quite a bit and checked out the maps—everything looks good to go. I'm not totally sure about the jam rules or if you even have time for this, but I’ve got a few tips for you!
If there’s one main thing to tweak, it’s the visuals (and nope, it doesn't need to be fancy, just something distinct). My best advice is to use easy post-processing filters—literally the same logic as putting a filter on an Instagram photo. You can use stuff like RGB split, film grain, or cinematic color grading to make it way more aesthetic with minimal effort. Another cool idea would be dropping in a quick new mechanic to spice up the gameplay dynamics—maybe something a bit trollish, or even a basic portal mechanic (if the scope and jam rules allow it, of course).
That’s pretty much it from me! It definitely doesn't need AAA graphics, just a unique look that has your own personal signature on it. Let that creativity flow! The game is already awesome, best of luck!
