I am working on a small smartphone (Android) game where you fight either against a bot or one friend local. You play as a ninja and can customize your abilities as you wish, to try different builds and find your best-winning skill set!
The goal is to hit your opponent while at the same time avoid his skills, similar to a bullet hell game. Different-strong skills require different amount of mana so you have to be careful when spamming.
What do you think about the idea and what could I improve? Right now there are 9 choosable abilities, with 3 different levels. On each level you can choose 1 of the 3.
P.S. How can I adjust the size of the picture?
