The game looks great and is super juicy. I would have integrate the opening/closing doors in the gameplay loop. Maybe you would need to solve a simple puzzle in the room before being able to open them? Otherwise you feel like you have no agency.

Hey that's not a bad idea! I am already improving it a bit, I added a lot of polish, like shadows under grenades and characters, an animation when pushing the objects rather than teleporting them one tile. And a teleporting animation when entering / leaving a level.
I though I could make it a game inside a weapons factory or something, and making this one of the different kinds of missions. But puzzles to open doors is a great idea and I'll definitely look into it!
