Mythmallow

A top-down arena shooter roguelite in which you're a mythical marshmallow fighting against peasant munchies such as chocolates, jellies, or candies!

Goal

Mythmallow is created after playing excessive amount of Brotato as a Rust enthusiast. The purpose is to learn how to develop a game from start to end with Bevy using best practices, and share it with the community as an example.

Installation

Mythmallow is free and open source! It'll be released on Steam and Epic Games Store for a small price in the future for those who want to donate or want to have the convenience of having the game on a gaming platform.

For the time being, the only way to play is to build the game yourself. The game is still in its infancy, so the release process is non-existent.
