The concept is interesting! I really like the red collapsing room system, though it made me panic a bit! Its gameplay is simple yet addicting, not to mention the sound effects are very satisfying. Some mechanics were confusing, it took some time for me to understand, and I finally managed to escape. I think you already know, but the main menu could use more polish to match the rest of the game. The buttons have a bit delay too. Also, this is just my opinion but maybe you can make the character face the direction of your cursor. So the player can just stand and still be able to attack in any direction. Overall, this is already impressive, I can see this getting expanded further with more room layouts, puzzles or enemy variants! Thank you for the fun experience!
