Camera being fixed makes this disorienting to play, but I seem to have got the hang of it eventually! Got up to #2 on the leaderboard! Looks like there may be a memory sink, however - the longer I played, the less responsive enemies got. Sound began to cut out and lag and the entire game became very slow when trying to enter my name for the leaderboard. Very tricky enemies. Maybe start them out a bit more slowly, so the player isn't being killed in the first few seconds. Once I had some time to move around, the game became easier!
Good use of simple UI/art, sound and a core mechanic to create a cohesive minigame!
