Thanks for your feedback! I'm really glad to hear someone made it all the way to the end. Did you notice that you can interact with the final surprise too? I realize it wasn’t very obvious, I never actually hinted that you could play with it by pressing E, and something extra happens if you interact multiple times.
I’m also a bit concerned about the difficulty level. I noticed some players struggled with things that were meant to be super obvious in the tutorial. So yeah, it really makes me happy to see people actually enjoying the full game!
If you enjoyed it, you should definitely try the Portal series. My game doesn’t even come close, those games are masterpieces.
As for expanding it, I have some other goals and priorities at the moment, but you never know. I might even turn it into a multiplayer co-op game someday since making multiplayer experiences is actually my main thing.
