It's harder than it seems!
Yes I agree that the traps are quite annoying but without them this game could be pretty dull. It took quite a bit of time to get this game into playable shape and I know how many prototypes he went through before the final product. For somebody's first platformer, I would have to say this is pretty good compared to other garbage some people will throw at us. So give him a break and don't let this game discourage you from playing his future ones.
