Thanks for dipping your toes in the game-creation space!
I was reminded of Stanley Parable and Exit 8.
The game was easy to finish, I liked the "twist" at the end, making me feel clever.
Lighting is somewhat weird, but I know very little about Godot, so I don't know how to fix it. Maybe more scattering? More "bounces"?
Having the hum of a lamp be the only background noise was... a choice. Some music would not have gone amiss.
It seems like you created all assets by hand, which is admirable. I for my part would just have used 3d assets from somewhere, but then again, I did not participate in the Jam at all, so who am I to make suggestions?
Overall, it was a fun, short game, and well-executed for the first attempt at a game jam. Hopefully, we'll have you again next year.
