its a really fun and creative game, and i like the freedom in it. some advice i'd give you is to make the background less confusing and flashy when your holding down the move buttons to sprint. Also, i would suggest that you add a tutorial, because i didn't know what to do when i first started the game, and i had to look at your game page to find out, and also i still don't know what to do with some items (eg: the shovel), but having a simple tutorial would fix that. Also, one last piece of advice, could you please add in a title screen, this would also help with letting the players pick if/when they want to do the tutorial.
anyways, it was a really fun game to play, and i hope you keep on making updates on it to make it so much more fun.
edit: also a mini map would be really cool and useful to the game to help with navigation (:
