What really struck me when I played Gator Raid is that this is an incredibly complete game. Normally you expect some programmer art, placeholder assets or unfinished mechanics in Game Jam games, but there's none of that here. The design is incredibly cohesive. I wouldn't be surprised to find something like this for sale on the Switch (if somewhat expanded).
The difficulty was a bit much for me, but I'm bad at these kinds of games, so it probably is just me. I was able to get through it, but a few levels took me a lot of tries. There could perhaps be slightly fewer instant death spikes, or an opportunity to look at the level map for longer. The gamepad support was nice, though.
The art is great. You've really pushed the palette to its limits, I feel. Also, the design of the main character is very cute, and that's always a plus with these retro platformers.
