Thanks ! I'm really glad you liked the level design. I'm not gonna lie, your comment brought a smile to my face. It's one my first puzzle game so I'm really happy to know that you enjoyed the mechanics, the level design, the revelation and the gradual progression as it the major points I focused on and I wasn't sure they would all be good (especially the revelation and the gradual progression).
As for Thomas Was Alone I discovered the game thanks to your comment and bought it immediately, I will for sure be playing it soon !
