The ending is absolutely amazing.
I loved every aspect of it, from the 'built to scale' aspect of it to finding keys, pressing pressureplates and what not. It is definitely a really fun game that I would also play if it was a full release type game. I hope that it maybe some day goes to that point of publishing. Great job on the level designs, I would add more props around, but the SFX and everything fit each other so well. Goodluck!
Do consider visiting our game :)
