Was a little unintuitive to start with but you do figure it out fairly quickly.
Adding some control over your builds would've been appreciated, as is it felt like I had to spam the reset as fast as possible in the hopes of getting as many damage and attack boosts as possible. The early rounds also were quite slow to play through and with limited options made it feel like I was missing something.
Still, was an interesting idea and with some polish could be quite fun.
