NOTE FROM DEVELOPER:
This game is a small project I put together while writing code for a custom 3d game engine I'm writing for a much more ambitious game. Even though this is a small project I created for testing purposes, I found it to be very fun and addictive; decided to release it publicly. As such, I plan to support Quadri over the coming months. A 3d paid version is also being considered once my game engine is further along.
