Awesome work for your first jam! I would say that the player movement felt really floaty, which tends to make them feel less responsive. I like what you were going with for the map, but it was weird to have it take up just half of the table. It seemed like there was a whole other area outside of your view where stuff could be going on. On that note, often enemies would die immediately as the spawned if you were shooting in their spawn area. So, sometimes I had the kill effect/sound when I didn't see any enemies. I also wasn't sure if they were spawning off screen in the other part of the table that I couldn't see. Still, great work!
