its nice, but kinda boring.....
its a good first game, any future attempts should include more to catch attention and keep people interested. like powerups and whatnot. i played and it was ok.... for about a minute... but then nothing changed beyond the normal 3 blocks i was dodging, that got boring so i quit, it caught my attention, but it couldn't keep it, so maybe pace the game a little faster as well. then this'd be lots funner. good luck ^^
