I didn't understand how to play :c

A guided on-screen tutorial would have helped a lot to understand the game. Too bad there are no sounds and visual feedback. The idea is still interesting!

Don't worry, it's just not explained in this version.

Imagine the mechanics of a MOBA - energy ~ health, stats that affect abilities. The tile you choose determines what ability your unit is using. The twist is that when you use the ability you can potentially transfer energy to your teammates.

 I will definitely put effort into a great tutorial in the future!

It's too hard to understand for my small brain :(
