Hey, solid little game here! Everything seemed to work well and I didn't encounter anything that felt buggy. I thought your main mechanic of unlocking movement keys was an interesting and unique idea, and your level design made good use of that mechanic. I did notice that in one place (corridor with platforms moving up and down, spikes along the top), it felt like the only way to pass the obstacle was to purposely clip through the platform colliders, which felt a bit bad/unintentional. I'm guessing I probably just didn't figure out how to time it as intended. The only other suggestion I'd have is that while your background textures look cool, in places like the title screen ("Unlock & Key" title text) and the controls menu, the text was really tough to read against the busy textures. Putting a UI panel that is a solid colour or is semi-transparent behind the text could be an easy fix here. Otherwise, I had fun and found all three keys, and successfully escaped! Nice work on this!
