Initial bones doesnt show up.
Make tower stats show up when hovering over each tower.
Add an option to show stats on skeletons, more info about the next wave.
An option to pause the game while upgrading towers could be useful.
Comparing scores to other players would be awesome.
Through habit i clicked return to lair hoping to return to the game (alot of games say return to game, more my fault though)
Earning score for being in max speed never went above 0
When you dont have enough bones for something, a cheesy line like "Grind more bones" would be good
Only reason i complained so much is because this game is awesome, huge potential and im addicted :)
