Hey there! Fun experience.
I think I completed it, I wasn't really sure. The music changed and there was a balcony I could run around on. The game might benefit from an ending screen or at least some text somewhere to let the player know. I also thought the checkpoint elevator was also a bit confusing. It seemed to me that it only goes up once? Thankfully the game saves the checkpoint, so I ended up going to the main menu and loading in again to bring the elevator back down to the bottom whenever I fell down.
The outdoor scaling was pretty tense! That was probably my favorite part. I really enjoyed the outdoor fans and resizable beams. I also thought resizing openings in the walls was a clever idea. Nice job!
