I liked the concept and the puzzles were fun. The art was cool too!
It would have been nice to have a checkpoint after falling into a pit. Having to restart from the beginning each time was a little annoying.
Also, I think I ran into a glitch. On one of the levels I made it to the end with both the robot and Mike and it appeared that I still could control the camera with WASD, which was strange.
One super small nit-pick: I felt like the dialogue text was a little inconsistent. In the starting cutscene it was really fast and hard to read, and then in the elevator it was slow, but the ability to load it all with space was nice!
Overall though, it was a fun game!
