Nice game! It was really fun to play!
It could maybe use some sound effects or music, because it's kind of quiet right now. Also next time you upload a game you can put the files into a .zip folder before you upload it so people only have to download one file instead of two. Also you shouldn't have your game page completely blank, it looks more professional and inviting if you fix it a little bit with a background and header etc...
But I think your game is very fun! Very interesting concept!
