Wow, I don't even know what to say about this game, this is by far my favorite TD game, now if it could only get an endless wave mode. 5/5 Is an understatement.
A good game overall, BUT there should be a warning system for items that can rip off body parts, such as the aggressive reaction for the fan, rips off the jaw, so now I have to kill it to get advanced reactions with food.
If your companion goes down, just kill everything in the room, then save and quit and he should be standing up with you when you reload, + if this helped.
If you need cash, go in and out of the town until you can get a blessing stone, a water stone, and an earth stone from the witch and compose your weapon, armor, ect. for drop rate a few times, then go on a killing frenzy and sell all your drops
