Итог 

ставлю 4 за все

I liked the simplicity of the game and it's attention to tutorials (pausing the player to allow time to read). I had fun playing through it.

Very nice! The game feels really polished, especially with the freezing when having to read or when you're falling into a new section of the world! Congrats :)

I love it! Simple and really well designed levels for a precision platformer, the mechanics are communicated really well and the frequency of checkpoints is on spot to me. Really just missing sound, but even then congrats for getting so much done in this short time frame!

I like the minimalism in the art. Honestly even in full games I prefer simplicity over details.
And here pixel art is implemented on a high level - respect +

Also, one thing is to come up with a mechanic and the other is to make levels for this mechanic. And in my opinion those levels are great. Short, simple but smart and support the mechanic.

I wish there would be some music and sounds. And it can be a full game with more levels.
