I really the artwork, it is really clean, I like the colors, and the animation is fun. The music and sound fits really well and I love that you move the unit around though it was not clear to me at first (maybe add a how to play on the itch io page). Once I understood that you can combine your units to make them bigger and stronger, there was nothing that could stop me! Really ! :D But please, please, make it more obvious maybe with a tutorial level that force you to level up your unit by combining them for dumb people like me :D
