I've completed it. I collected the 10 keys and understood a little bit despite being it entirely in portuguese. The controls are really good, I liked them a lot, but some graphical aspects were kinda a headache; the pistol firing almost gave me epilepsy (jk).
Anything other than that, a 3D game under a week is a feat! It's also done in coppercube, I didn't expect that game engine to play a role in this jam. Keep the good work
