Please add the button "Buy All" for cash and angels upgrades.
I make a reset every day and I'm tired to click 1000 times on the same button...Also i think its time to add button "1000" for buying business
I think that in such a game should be a section Statistic!
It may contain:
how much money is earned per second / minute / day
how many angels attracted per second / minute / day
how much money has been earned for the day / all the time (you can add graph)
the date when the game started
how many mouse clicks was done...
and much more of interesting information!
this section as well as its sub-sections can be opened with money
Good game, but to easy...especialy bosses...I think bosses should shoot thousand bullets or use special attacks, from which it is necessary to hide. And I think that regular units should become more and more with each wave.
