Controls
My main problem with this game are the controls. Its my belief for any game that the arrows at which you use to move your characters should NEVER ever be used to make your character jump. You have 100 other keys on the keyboard that a player can press to make the character jump. Why would you choose the up button of all buttons you have available to you to make your character jump? it doesnt make sense and it makes the game needessly difficult in ways no game should ever be.
Anyway, now the game itself is actually pretty good. Its fun, its pretty entertaining and from the little bit ive played was pretty fair on the difficulty. The graphics looked pretty clean and were smooth and the music worked for it really well. So i'll give it an 8 overall.
Just keep the controls in mind for future projects to come. Good work!
