Easily beatable in under ten minutes. The gameplay is eerily reminiscent of Geometry Dash, except without the limitation of needing to play to a beat... good thing, too, since the buttons aren't immediately responsive after landing, making successive jumps difficult.
There is a minor glitch you can perform to make the game marginally easier on yourself, if you're having trouble clearing more difficult obstacles: you can essentially "super jump" by pressing any two keyboard buttons almost simultaneously (but not exactly at the same time, or they won't both register). In doing so, your square can jump as high as the top of the screen, making any obstacle seem less daunting than it really is.
You can take this one step further by, of course, pressing THREE buttons in extremely rapid succession, causing your square to leap well above the boundaries of the screen. (Be careful in doing this over some moving platforms. Your momentum may end up carrying you right through them.) However, if you can trigger this consistently, you can even clear large gaps such as those in Levels 11 and 12 (with the moving platforms you normally need to land on). It completely trivializes the game once mastered.
