The concept of skills and specific character trees as well as trap upgrading is really a great addition to this game and the series.
The fact that that about 70% of the traps are ceiling traps when there are almost no ceilings in the game is where the developers really screwed the pooch here. The level designs are generally hit and miss with older games in the series, but Orcs Must Die: Deathtrap is almost entirely a miss.

If you are going to make us play through this game that is for the vast majority of the campaign outside or in a wide open area, make the ceiling traps place-able on the ground at the very least.

Also, there was a barrier limit added...bigger levels..almost non-existent ceilings..and a shared barrier limit REALLY constricts the way people are use to playing the game. Nobody asked for this.

Alright, well I never played ODM until this game despite what the reviews said to do.
*Solo player
*Barricade it up
*Only traps unless there was a breakthrough

I can get to the sixth map on 1 skull before the health pools become ridiculous (haven't maxed out all traps and skill trees yet) and I would say that's my biggest complaint.
Most games scale with enlarging health pools and I don't mind that in a limited scope, but it's ridiculous when the grunts have 6k health bars. Just make more enemies, that'd be sooo sweet.
Also can you make it so that the orc bodies last longer, or make it an option pleaaasse i'll take full responsibility if my computer melts through the floor, but it's just not satisfying how quickly they go away.

Humm what else..
Map design is meh, I only recently figured out you can switch traps part way through which I'm sure leads to strategies when you're playing with multiple people.
Most of the traps are satisfying and fun to try at least once, making combos with them is very fun.

I wish there was more to the combo system though. Like an enemy covered in acid would combust to some degree upon hitting fire. Fire, ice, acid, tar, electricity, poison.. so many elements, but 0 interaction with each other.

Anyway, I've said enough. It's good enough to have gotten 30 hours out of me so you should at least try it.

It's fun, but it feels like an early access title without the early access tag. Missing the features of the old games, game crashes, lack of different modes, and limited maps all make this title inferior to the games before it.

It's fun, but wait for a sale to buy. Probably like minimum 50% off.
