It took me some time to understand how to play, but it's a nice game! I like the music, art is good, the only thing that confused me were the collisions and damage, I still don't understand for example if the snake can kill us or what.

that you for you kind words and will update based on you suggestions

This game is cute XD
I love the musics and the art style XD
The ending is funny too. I like it XD
If you play the game again after beating the game, somehow it just continue do the ending while getting beaten by the enemies. Which is weird but it's still fun to watch XD The game became unplayable after that though :'D
For the last level, it's quite hard but I manage to cheese it with staying in the up corner where the enemies can't attack. From there I just keep spam shift while dodging the snake demon. I think rather than increasing the number of enemies, you can put a moving platform or see saw platform to make the game more interesting.
