It's a really good idea, but I think it would have worked better with several shorter levels rather than one big one from the start. I hesitated with my first robot, so after pushing all the buttons I realized I didn't have enough time left to go push the last one and had to redo the whole right part of the level. It's my fault but it is still a bit frustrating, and I think you can expect that to happen as people are discovering your game. The art style is neat, clear and clean, I like it a lot.
