Have you played demon queen's possesion? can you clear it?!
Demon Queen's Possessions
Its 25 lvs, but most people gets to 12~15! can you step up to the challenge?!
Its a game about blowing through waves of dangerous (and not so dangerous bystanders) foes. You can use your units to attack your foes, or sacrifice your units to possess your foes.
From peasant to Hero, passing by Goblin, nothing will be spared. Use your cleverness to Create spirit value from "nothing". (You'll see, it seems like you can't "grow" your army, but you can! It's tricky though)

Just got quite an optimal(Least kill possible) playthrough so I thought I'd challenge any competitive people to beat it.
My Best!
(got to wave 23/25 before being forced to kill... So CLOSE!!!)
The Art of sacrifice & possession is a puzzle in itself, but here are some hints! - You can possess multiple units at the same time!! - Goat has the ability to increase its spirit value. - Sacrifice & Possession > Fighting. By a lot actually, you can almost not fight at all. - The campaign is 25 levels and they are always the same: Yes you can "Learn from playthroughs" to optimize approach. - You can split 1 high level units for many lower level units, The stars must match, but dont be afraid to downgrade.
I'll be playing some more games today, but in the meantime, I hope a bunch of you get to try this one, It's a nice challenge! Feedback would be appreciated!
