I gave the game a try and must have messed something up as the blue key ended up disappearing completely and I couldn't get poptyre to allow me to try get it again. The idea is certainly interesting but I think it needs a bit more thought put into how you'd foolproof it so that issues like that don't happen. It seems very much like a game where you'd have to use set types of progression to get through it.

I did try to record the game however I ran into issues with doing so - it just kept recording black screen instead of the game window, even when I made sure I was clicked on it. That's a bit unfortunate since it showed me losing the key and messing stuff up, but welp! It's certainly not a bad proof of concept, just has a few little bumps.

Pretty good. I'd enjoy seeing this expanded because as is, there is not a ton to do. Also, the game gets a bit confusing after the first two keys. Still, this is a simple, and largely, straightforward game with a lot of potential that people should try out :)
