A small prototype game, made for a lesson.
Made in 4 hours, with the subject "Rock, Paper, Scissors"

Super Awesome Triangle is a small scale versus fighting game.
Two awesome triangles fight for supremacy over the rectangle land.
To do this, they battle with their body, shield, and magic, trying to vanquish the other.

As hinted by the subject, the three actions defeat another one, and cancel themselves.
Attacking is blocked by the shield.
The shield doesn't protect against magic.
And magic cast can be disrupted by getting attacked.

The game is two players only, as it is made for versus.
