Solar Gun Gameplay -A Steam game under $1-

I buy Steam games only using Steam Cards, because I don't trust anything with my bank card. So whenever I finished purchasing a big game I wanted, I often times search for what games I can buy for whatever pennies I have left in my wallet.

Solar Gun was one of these purchases, and it's not a bad little puzzle game with obvious Portal inspiration. The game is extremely short, but then again, it only costs 99 cents.
