Nice little game! Clicking the trap doors were a little fiddly and it took me a minute to work out what the block was that spawned when I pressed the button. (I ended up with loads) I love that you made the classic physics exploit a feature (I'm guessing you like gary's mod?). Nice one!

for 2 days it's good (and dare I say your first game?) I just couldn't go far, where is that button that I should be clicking to make blocks? I did click on the empty square but nothing happened. also I thought those red square spitting thingies were save points but they weren't. but what is great is that you did it... can't say the same thing about myself!
