Screenies look very nice, however whenever run it I get the whole "unexpected error" thing. However, I think it's because I don't have enough free memory. I'll free some up and try again.
EDIT: Shut down Firefox, iTunes, and Photoshop, which I swear are the most memory-hogging programs on earth, and when combined create a demon that has no other purpose but to transform yur computer into a sluggish pile of crap, and played it again - and, WOW, you have acheived a completely professional quality - everything was nice and spiffy, but not too bloated or fancified, all the tiling is also like that, the sounds are
awesome, and overall the whole thing just seems very professional. Honestly, if I had bought a GBA game and that was it, I would not have batted an eye. Even though I hate rating, I have to say, 10 out of 10 stars so far.
The only improvements I would suggest are:
-When he runs, have him get to max speed a little faster. It takes a pretty long strip to get to max speed, or what seems like it, and there aren't many opportunities to do that.
-Make the speed that he moves (sideways) when falling a little slower. I died numerous times because I dind't realize it and was too late to move in the opposite direction a few times.
-And ( though I assume this was already in the plan) replace the unoriginal sound effects with original ones.
I would actually suggest selling this game online once it is complete. It's incredibly good.
EDIT #2: Also, I uploaded it to my regular file host, not my server, but whatever.
