Was starting to be fun until towards the end with several really annoying missions. Getting caught off guard by new monsters that would make me lose the mission within several minutes into the start on NORMAL was not fun. Got sick of trying to make the game function and let me place towers on the map because of the UI being in the way and making me place towers down in bad positions without being able to refund them. Didn't feel like doing the weird timed challenges for extra skill points because they quickly became too unfun.
