I really liked this game. The theming and visuals were both great. The janky platformer was the fun kind of janky, and served as a pretty damn effective segue into the core of the game.
The auto-battler RTS-ish mechanics weren't immediately intuitive, but I did get them pretty quickly. Mechanically, 'healer' and 'builder' make sense as names, but flavor-wise the builder is also healing, so those names were a bit confusing.
I will mention that the file you uploaded was Window-only, even though you marked it as Windows, Mac, and Linux. Just make sure you're more careful with that stuff in the future.
