The simplicity of gameplay and the inclusion of both tactics and strategy (and upgrades!) makes this game my favorite on itch.io.

Although by personal preference I'd suggest forking the project and making it into a simple RPG. Add a basic story line (saving the kidnapped princess), remove store re-rolling/randomness, make basic units/weapons always purchasable, unlock higher tier units/weapons with progress, and then release on Itch & Steam!
