Now that judging is over, I am finally free to talk about this game.
Among the entries, this is one of my top 5 favorites.
There are some issues with the presentation such as the maps being too dark, minor spelling issues, the text is pretty hard to read and terrible GUI. Some of the mapping could use work and there is that one annoying ice level which isn't helped by major lag issues due to the lighting script. Don't get me wrong, despite my complaints about full screen and such, my pc is a gaming pc aka a beast. This isn't normally a problem but when RM actually chops with my specs, you know that this game has performance issues. The good music choice is enough for me to keep trudging even when there are some audio issues sometimes.
BUT, it is one of those games that knows its premise well and sticks to it. Cutscenes won't help this game a dime or any interaction from useless characters. It's a game about how the other side of the coin works, so to speak. It's the side where we don't usually see in RPGs (which I believe is the reason why the game's title is even backwards). It's the side of the monsters, told by a slime that eventually becomes a Demon Prince to succeed the main antagonist. It's about how dysfunctional and unemotional that side is compared to the hero side. This game also has amazing humor thrown in without destroying the plot. Overall I liked it and I wouldn't change anything to how it's conveyed.
Gameplay-wise, the mechanics are simple but interesting. The timed attacks get old really fast. Missing even after mastering QTE is even worse. The final dungeon gets annoying. Adding stun on a single player game is cheap. Too much touch encounters, but I can see why they did it, it's the theme of the game where heroes infest the dungeons to get stronger and finally defeat that one evil lord. I love the whole you HAVE to die and get powerful, it brings the point home to the main plot. The fast pacing is awesome and I really enjoyed this game.
Do I recommend this? Yes and No. It depends on your preference. But with my circle of friends that get bored easily by RM games, this is one of those rare games that don't.
I would love to see this remade (or I'll do it for you developer-san if you're lazy).
