So this is an interesting one.
It's honestly a really basic turnbased rpg but there is just something to it that just kinda works. The atmosphere is kinda suppressing and it sometimes really does get a bit gruesome graphically.
This game does not break any boundaries or something like that. It just kinda exists and is a neat experience I return yearly for no real reason. It is an short experience. If you know what you do you can play it through like 4-6 hours.But there is really no reason for me to like it that much but I still do.
But if you wanna play something obscure from the DS and early Mobilegame era, try it.

Underrated Game of the SNES era.
It looks a bit shallow on the first view but damn, there is actually a good bunch in this. Most levels have an alternate way with an alternate boss, rewarding you with diverse items that will either boss you a bit or a gem that changes what ype of demon you are which you use depenig on the situation.
100% this game for the first time is hard, there are enough bosses that do not joke around. The levels are mostly also neatly done but there are a few annoying places.
The presentation of how everything looks and to that the Music makes it really an unique game and is also fun to speedrun for fun.
Please give this game a chance somehow. It really deserves it.

An honestly good game. It's simple from the gameplay standpoint but this was probably not the first buy reason. So seeing that the fights and rest of the gameplay were pretty neat was a welcoming suprise.
South Parks writing was always on the aggressive darkhumor and sometimes controversieal site, so this really isn't something for everyone like the series.
But aside that it's really charming and hearing all the original voiceovers even in other languages (In my case German) was also a bit suprising.
So as an fan of the TV Series you should give it a try.
