This game was a lot of fun! The idea of needing to move around to charge your attack was very creative.
Some of the maps felt a little cramped, like there was no place to get cover. Which I guess maybe was intentional, but there are weird difficulty spikes because of it. Also, in the upgrade shop, for some reason I was always offered the same skill for the first & third slot (e.g. both would be "get more gold"). IDK if that's a glitch or if it's random and I was just getting unlucky.
I love the music and sound design!
