Slick visuals and music - and main character! Overall, the gameplay is indeed confusing. I'm not sure exactly how to remedy it, but something about the way the upgrades, swaps, and plays are all *presented* the same way seems to be the problem. The typed text up top attempts to clear up which action you're taking, but the actions all being framed in the same list of 3 every time doesn't help much.
The concept and art are there - just needs a bit of onboarding! That's a good place to be in my book.
