Purranoia
Purranoia is an action roguelike with a twist to the genre - you have no control over your characters movement. Instead you control a variety of powerful scientific inventions to protect poor cat Mousti from waves of enemies.
Story:
“It’s crucial to understand that Schrödinger’s cat is a thought experiment, not a real experiment that was ever performed or intended to be performed. Until…”
A mad scientist uses an innocent cat, Mousti, as the subject of a dangerous quantum experiment. Mousti must survive waves of mutant lab mice and other bizarre creatures, using the scientists own inventions. How this chaos advances science is unclear, but the scientist seeks glory, and Mousti holds the key to the experiment’s outcome.
How to play:
- Select an ability when you start the game
- Aim your ability to fight off enemies
- Each time you level up, you get to either pick a new ability to add to your arsenal or an upgrade to an existing ability
