with some polish this game could be better. i give it a three because i feel you worked very hard, and you can and will get better with more practice. i enjoyed playing until my first death bt not long after.
this needs:
some music and SFX,
some more enemy types
some better graphics
graphics and sound dont necessarily make a game, but having at least some of them is nice you know?
good job for your first game. keep precticing.
