Its a pretty simple and great game, there are a few things that would make the game better tho, for example more sound effects and more feedback, for example sound effect for when you get hurt, or feedback on when you get hurt, footstep sounds etc. just something to add more life to the game, and also with the random spawning there is a small problem that happens sometimes, which is that the lil demon guys can spawn pixels away from you, and if you're moving in that direction its bascially unavoidable since you cant react quick enough, a good way to fix it is either to spawn the enemies away from the player or a better fix, add like a square in the place that they are going to spawn 1 second before the enemy will actually gonna spawn there, that makes it more predictible and eliminates the "spawning too close to the player" problem since the player can now react in time, an idea that i just had is maybe making the headbutts boost your movement speed for the time that you're headbutting, so again there is feedback on when you can actually kill an enemy with it since sometimes i just headbutted but i was too late to touch an enemy so i just lost health, other than that, i really liked the art style, especially the thumbnail for the game, its pretty cute, good job on finishing the game, hope my feedback was in any way, shape or form useful!
