I got all ending pretty easily but I really had to try hard to find the green man (I'm still not 100% sure what exactly triggered it), but that was worth it as this was the craziest endings in a game that's didn't lack craziness. This game made me laugh a lot and I got caught by one unexpected jump scare (not even sure if it was intentional).
The graphics are also very cool and I loved the ambiance of the different world.
I believe I encountered a bug when leaving and reentering full screen where the pointer became suddenly imprecise (I could not interact without being in motion). Not sure if that's worth fixing if it's just me, but I thought it could be useful to let you know.
Thanks for making this game, you made my evening. Good job!
