Honestly it was pretty buggy for me. Took a long time to boot up for the first time, the menu gets bugs out when you select any option. I clicked on "Controls" to check how to play and every time I clicked on "To Title" or hit Esc it would bring me back to the Controls... While playing the game the space bar would not make it jump so I couldn't do much past getting the eraser. I do wonder what the objectives of the game are?
Don't get discouraged though, it could work into something fun, but right now it needs quite a bit of work to reach a more polished playable state.
