It would be great if the summoned skeleton would follow you to other rooms. Currently, if you spawn it in, once you kill all the enemies in the room the skeleton just stands there, unwilling to come with you.
Actually, my armadillo hasn't stopped and won't stop bouncing. I thought it would have stopped bouncing by the time I finished the previous comment, but it seems to be stuck in an endless loop of bouncing. R.I.P. getting those achievements.
It would be great if you could add an "End Round" button so we can get back to the upgrades/achievements screen. I just spent around 3 minutes just waiting for my armadillo to stop bouncing.
Aiming is broken. When you try to kill an enemy that is on the bottom 3rd of your barrier, you just cannot hit him. I died 2 days in because a zombie rottweiler was *just* below where the game allowed me to aim.
