I am really glad that you enjoyed the game, there was an ammo count on the bottom right corner, but you are 100% right about the wave count, I will be updating the game after the Jam is over with that. Also yeah I didn't want to restrict the player's vertical movement but infinite jumps can be used to kinda break the game, so maybe I will limit that to 3 jumps or so, or perhaps even better a limiter to stop you from using jumps once you reach a certain height. Thanks for playing my game!
