Basically my first game jam and one of my first "games" - though its way too buggy, has annoying unclear things like invisible walls on the side among some other nonsense.  Don't even know why I'm posting it here but https://infinitymatrix.itch.io/marine-wars

It's okay! Its my first game jam too :). I really liked your game's idea :)

hey, don't worry about it! i doubt that it's even possible to create a bug-free game in such a short time. 
that's what jams are for - learning and improving.
