Idea is good, exec is not bad if made in haste.
Pixel view is neat. Full mouse control could be better.
Human animations are a bit exagrrated.
Enemy health bar is a must.
2 Way points - need to posses 2 different weapons at the same time. So possession can have some time limit, I can posses 1 and let it on auto, go and posses another one.
Music On / off.
Didn't play much, those are my experiences.
This game is promising good time with a few tweaks.
