DRTM is a horror-survival game set with unique enemy detection and upgrade systems. The game was never finished, and its being released here for others to play and look around.
A full writeup on the game is available here: https://minmax.miraheze.org/wiki/Don%27t_Ruin_the_Magic The game's successor, Min-Max, is currently being worked on in another repository.
There are two major commits to consider, the "October Patch" commit provides the last version of the game before it was dropped for Min-Max. The current commit, "V2", changes the codebase and levels as an intermediary prototype between the two games, before it was ultimately decided to drop the codebase and start a new one for Min-Max. You may want to download the October commit instead of the V2 commit for the proper experience.
There are four archived builds in the Assets/Builds folder. None of these are of the "V2" commit, but are of the October and May commits.
