Nice game! The art style is so clean and elegant, I really like it :). The little animations they do and the nice background... Enjoyable :D.
The idea is quite cool, I like how you exploit the enemy movements :D. Maybe the enemies could move a bit less randomly, but not sure how that would work. Would welcome an option to hold a button to keep moving in a direction.
I find all the crafting quite linear. Open all the chests, get the new weapon. Perhaps some more decision might make it more interesting. But I like that you can see the weapon on the player and that you're getting stronger over time :).
Sounds: great soundtrack :), but the move SFX gets repetitive.
Bugs: The music didn't play the first time. Sometimes enemies get on top of each other. Sometimes you get on top of an enemy (when moving fast?).
Overall, it's a nice game! Well done :).
