Thank you for your thorough feedback!
Yeah I feel like this would be really hard to engage with on a trackpad - that being said the mechanic absolutely needs some refinement and polish.
Personally I really like the 2 choice progression cadence. If I were to do this again, the hope would be to have more choices, that were maybe smaller, but more meaningful, e.g. you can choose to upgrade an existing move, or get a new move, but if you don’t choose the new move it never shows up again.
Anyway thanks for playing and for the thoughts!
