Invalid Tangram is a unique shooter game created by a game developer named Josh Szepietowski. The game combines a shmup with Tetris as the player needs to collect falling blocks in order to gain weaponry. There is a plan to port Invalid Tangram to the Nintendo DS.
In order to get weapons to fight off the onslaught of enemies, the falling blocks have to be collected. Each color grants a powerup that lasts for a limited time. If blocks of similar colors land on one another and are collected, the powerup will last longer and have a better effect. Each of the powerups are stackable.
- Red - Rapid firing bullets.
- Yellow - Increases the number of bullets.
- Green - Makes bullets homing.
- Blue - Makes bullets more powerful.
