No Music? C'mon!
If you think music and sound adds nothing but file size, then you know NOTHING about this sort of thing, do you? You can make a fun game, but music and sound is the heart and soul of any game, movie, or book (yes, I said book).
So, yeah, it would've been a LOT more enjoyable if it had music/sound, oh, and fix the wall jumping, it's just too frustrating =/
3/10 (minus 5 points for not having music/proper wall jumping mechanics).
