I think the controls are somewhat odd. (or I am bad at platformers) Maybe a control scheme where your inputs aren't as spread out would fit better like arrowkeys, c, x and z like many other platformers. This way you can have one finger for each key. Despite this I made it thru the game which is great. The game feels very challenging so it is very rewarding to beat every level. Almost all levels introduce something new like a new jump or boulders, keeping you focused. Great game!
