Movement and the controls in general feel really good. The character animation and screen shake are great. I liked the levels, there was a nice increase in difficulty. In most levels there was an "aha" moment.
Some smaller nitpicks:
- the delay before aiming when holding the throw button feels too long
- if you get pushed by the angled doors you can't turn it again directly, instead you have to walk away from it and then turn around
- The blocks connected with the chain looked disconnected due to their independent movement
- At least in the last level there is noticeable aliasing, the walls of the room flicker when moving to the right
