Cute game ! Was bit hard to understand tho, I had to restart the game twice to re-read the instructions. I didn't understand the input to flip the switch and it wasnt clear that I had to pick up the gems to open the door as those are generally optional in games. Maybe keys would've been easier to understand ? I really liked the dialogs with the mysterious shadowy figure, unfortunately, I wasnt able to beat the boss since I would keep running out of ammo while the Boss had like 1 hp, so I had to give up, I don't know if I had any way of getting more ammo.
Cool game.
