I find this game incredibly well-made !
The graphics and sounds blend together seamlessly, immersing us in the game's atmosphere.
However, a brief tutorial would have been helpful...
PS : I'm having trouble understanding how this game fits the "On/Off" theme.
By the way, I noticed your username on all the leaderboards, so I assumed you'd also create a competitive game, but I was quite mistaken. Also, feel free to try out my speedrun platformer. I think you won't be disappointed ( I didn't have time to implement the leaderboard, but you can send a screenshot of your level selection menu with all your best scores in comment ).
