Not a lot of games utilize real-life objects to create interesting graphics. Imagine a game where the enemies are comprised of photos arranged in a mosaic, for example.
Post I.T. Shooter is one of these rare games, but it's not unusual to see this sort of game from Petri Purho, who is best known for
Crayon Physics. While the gameplay is nothing special, the catch is that everything is rendered in Post-It Notes. It's an interesting twist, and the pixel art is well done, if simplistic. The music is also hilarious, as it is some sort of mixture between a voice-over and lounge music.
You move around with the arrow keys, and attack with space. The only scoring is how many enemies you defeat before dying. You die in a single hit, so you must dodge every enemy shot. Enemies get tougher over time, and move faster as they get damaged. The hitbox for enemies is relatively small, and your hitbox is large, so be prepared to die quite a bit.
