needs an option to open the level up screen from play... I've had it skip the armor level up I wanted and make me wait for the weapon level up more than once
gave it a 4/5 good game, but really wish you could replay levels (even not for bloop farming, it could have a xxxx/xxxx note so you know how close to all of them you got... when I beat the game (second try) I still couldn't afford all the upgrades
glitch in outlands- the glacier... one of the glaciers has a "hole" on the right side of the chasm... letting you fall through without dying and stall out the game since there is no restart level button or any other way to quit in game mid-race
I like the game, but between the shot range being buggy (completely inconsistant, sometimes "distance shot" couldn't even go 2 inches) and the excessive lag issues (not just with multiple enemies on screen, but after the first minute or so of the challenge mode stuck in lag) just not worth the effort
didn't run into the "forget to take a move" issue, but Please make it easier to find the computer's most recent move, missed it frequently allowing free squares.
other than the lack of anything "new" to the game, I really really hate tower defense games where the towers have Horrible aim (watching a machine gun shoot behind a monster for 15 seconds till it is out of range and never hit it once, gets old fast)
