This was a fun co-op tower defense game. Emphasis on "was", because the developer-hosted servers got shut down.

For some ungodly reason, co-op was tied to said servers instead of simply being peer-to-peer or allowing for self-hosting.

For yet another ungodly reason, player progression was also tied to said servers so everybody lost their entire progress as well.

This is how you develop a game if your end goal is to slap your customers and players in the face. Frankly, this shouldn't even be legal.
