Just a test...
 

Bah...i got bored and was trying out some of these house tiles...

Can you see if i made any mistakes (the brick one is TOTALLY messed up...i couldn't fit those bricks up...)

Please tell me your just joking

Both are just really really ugly.. start over.

If you only want us to look at the houses then...
The first one to the left has been done before, nothing too special. You should also add, if not a door, at least black inside. The second house is just normal looking.

Ahhhhh....*turns around to bolt and runs into a wall and knocks himself out*

don't worry, I fixed the brick tiles and they're going up in the next update.

Tip: Try to spice up your levels with more original tiles. Add things together instead of just using the basic ones.
