Nice game, thank you. I don't think I saw a basic attack option without using skills. Is there one?
A few suggestions from me:
* You should include the tag "tactical" instead of "strategic". Strategy is usually about resource management (be that armies or virtual resources) whereas this type of combat is tactical. I'm a fan of this genre, I'm not criticising. You can play my game to see my take on tactical.
* It was nice to read in French but please note that English is a safer option. You risk losing people who would not understand the skills.
Good luck!
