Reid becomes the villain and corrupts the land!
It's a unique game for RPG Maker since it's normally not possible to change autotiles. It's pretty easy and fun to just run around the land corrupting all the things.
I did have some issues with the game though. The grammar and spelling made it really apparent that English is not your first language (though I was able to follow what the intent of it all was easily enough). The game's biggest weakness is backtracking: 1) If you don't go through the map with perfect efficiency you lose life. While the health bar is certainly generous enough to allow most players to recover from mistakes, it's still a little hair-raising to be going around and wondering "did I get it all?", which in turn means backtracking and losing life! 2) I have to go over the whole map multiple times. It was kinda fun the first couple of times where I was still learning where everything was and getting to explore more of the map with each replay, but by the time I had unlocked 3 or 4 of the helpers I had explored all of the map and corrupting the same parts again felt redundant.
So overall, I had enough fun to play to the end, but I almost put the game down before getting to the end because I got tired of going over the same maps again and again.
