Very good.
Graphics, response and music are all good. One problem i had was with the jump. The jump wasnt always reliable to be the same distance it was when i made the exact same jump i did in the play before. Plus some of the hills require the GOOD jumps, and a few make it to difficult. Not saying you made the game impossible, just that this problem really hurts the game play. Otherwise i couldnt find any problems.
when you jump, you still have to hit space to move
so if you stop hiting space while jumping, you'll just fall straight down
so the faster you hit space while jumping, the further you'll jump!
Frantic!
Yeah, I enjoyed it. There's not much to it, which is why you don't get a higher score, but the fast-paced action made me play for a while. Maybe give the player a few more seconds to react at the beginning; my character died before I even realised what was going on.
It's a good enough game though, music was nice, graphics were passable and I LOVED the fact that you could still stay alive on the debris following the lava, it was a brilliant touch.
Add a bit more to it - some more challenges, some different parts (bonuses, levels, etc), and this could be great.
ok, thanks for the ideas, i'll think about that
