Latest "update" completely reset all of my upgrades. And I lost all my prestige points. Boo! So when I figured it was kosher to shift+click and restart my reactor... BOOM! heat overload and I lost everything.
So far this game has been really great, but that experience was disappointing as I have to restart from scratch.
I would love to see some buy-all-available buttons for upgrades. And maybe expand the 1/10/100 to include 1000 or maybe even "max". Towards the end-game the amount of clicking you have to do to re-purchase everything is starting to get annoying.
Without any clear indication of how/when new waves will arrive or how to avoid working against yourself this game is almost impossible to play. Also - having the waves launch when you fire a ball, in many cases ends up colliding with your launched ball and ruining your shot. I've never rated a game 1/5 before - so congratulations on being the first at something...
