Hm... I hit the ball with the side of my paddle near the wall and the ball went into the wall and now it's stuck moving around in the wall! LOL. 5/5 very fun :)
When you reset character stats at a high level it takes too many clicks to allocate your points... Maybe add a button to place 5 or 10 points at a time? Other than that great job 5/5
Tip; you don't need to spend money to get coins, don't rate low because you're too lazy to work for your items. Also, the items you buy with coins are mostly accessories, so only skill matters.
Tip for survival mode: Get Level 3 Locusts, Reaper and Earthquake (Reaper and Earthquake can be any level, but higher is better). Save mana while floors 1 and 2 are built. Make sure you always have a Reaper walking around. Whenever floor 3 is over 10% built, cast Earthquake. Casting Locusts will kill the majority of the enemies coming your way, while your Reaper will kill the ones who reach the top. It is good to cast Locusts every 6-7 mana you regenerate, so that you always have enough. With this method you can last virtually forever. + for others to see!
