Burning damage and poison damage upgrades improves the towers with fire and poison damage? Is there any way to buy x10, x100...etc? What is start wave+ button?

As title says, someone knows what to do to get them? They are: why did you do that? still not enough? i think you have to much time i think it´s now enough blooooooooooooood

I found this game awhile back and saw it was becomeing F2P in the future so i waited and i'm glad that i remembered about it because i started playing it yesterday and its actually pretty good. I saw that people are saying its abandoned and if it is that's such a shame, Theirs so much potential in this....

yea hey i would start the game and as i would play is the cursor in the game slower as there on my desktop so i jump out of the game then the courser on my desktop is idk faster as ther in the game can someone fix it thanks...

I was just wondering if it is still possible to get 100% achievements in this game?
