Hi, cool game ! Not bad at al for a second game ! I really like the art and the gameplay is fun.
Perhaps in another iteration you could tweak the difficulty a bit (I feel like the game has constantly the same difficulty), perhaps increasing the spawn frequency over time could be more fun idk ?
I would also guess that maybe putting in some sort of reward (like a golden creep that would give you +10 score or something) would add a fresh touch, and setting the score to the amount of creeps dodged could be fun, but that's just my idea
Anyways, cheers on your game !
