This game might be a decent, but its marred by not having a cohesive control scheme. I couldn't understand the actual control schematics.
My advise for the future is to either have a tutorial level and go through the actual controls the players will need to press OR leave an instruction manual, preferably in game, but in the description would suffice as well.
An example of such is that the 'A' Key was actually [Z] for me. And I only figured that out due to my experiences playing GB games on PC
