I didn't like it. The player should understand how to play your game. In the first room, the head in the upper left corner is a box that needs to be placed on a slab, not a UI element. Furthermore, it turns out you need to press E when you reach it. Overdifficult.
The life counter is weird. If you lose, you start over. What's the point of all this? Remove this counter and just restart the room.
The double jump is poorly implemented. I managed to jump only once out of five times. A jump on W and arrow keys wouldn't hurt.
I didn't get past the second room.
