Well, the it's a game at least. The good'ol platforming mechanich is clearly there. But it needs al ot of work right now:
The character loses health even though I'm clearly not touching the spikes. I easily slip and fall off the edges of the platforms for some unknown reason. I miss a jumping animation. And the game itself just suddenly jumps to the "OMG! My shirt!"-part even though I'm far away from the flagpole. It also just stays at that part when it first comes up. I tried pushing buttons and clicking everywhere to proceed, but nothing happened at all. Is anything supposed to happen at that part? If so you might want to implement a button to proceed with the cutscene.
But all in all, this is absolutely bare-bones. The entire game seems to need fleshing out and polishing. You could add sounds for the jump or collection of coins, a quick victory sound for when you touch the flag and maybe some music that fits the mood.
So I'll just sum this up with this line: Please make something that is more complete before submitting it.
