I really liked the movement of the player, it felt really good! I also really liked the buckets as projectiles you needed to pick up again after usage.
Although, it was a bit hard to figure out you needed to destroy the spawner, I first quit the game after door 1, but after coming back and reading the other comment, I finally understood. So maybe a visual will help the player understand.
Also I would like to see the enemies keep spawning out of the spawners, since now you can kill all the enemies easily and then destroy the spawners without any threat.
I loved the direction of the game!
