The art style feels a bit inconsistent, not fitting well together.
I dropped a box in the brown area, but nothing happened. Enemies are quite frustrating to handle since they can only be pushed, and I kept dying way too fast -sometimes even losing health when an enemy was still far away. Also, the fire appears too suddenly, making it hard to react in time. For further games always have in mind: What is easy for you to manage in game, a new player might get stuck.
The game fits the theme, but the game play felt too frustrating, so I didn’t end up opening any doors to progress further. That's why I am not able to give any more feedback for your game.
