I have been developing some small games for 3 years. And I want to say my opinion. Everything is perfect here (I'm not flattering), I really like this game, the secrets, the collectible books and the character. It reminded me of wonderful and equally wonderful childhood flash games. I think that the game has potential and if you finish it, you will take your rightful place among the indie games of the world
(it's a bit like platformer levels with geometry dash 2.2)
