Very fun game. I really liked the Into The Breach style tactics. A thing that felt weird in the beginning was the ability choice, have you considered making it pop up above your character when selected instead of staying in the top left corner?
Thanks for the comment! I've considered putting it next to the character, but it was hiding the tiles below, which was an issue especially when clicking on a tile was still possible (when a character has not yet moved), too much risk of miss-clicks. But maybe I could make the icons "pop" more?
