good game, the upgrading system is very nice because it balances out the "spam space bar to win" mechanic (like cloud wars) but i would like a upgrade system like if you beat a level quickly or by losing a small amount of blobs you would gain 3 stars and you could spend those to increase reproduction speed, speed of blobs, attack power, defense etc.
reasons why this game is only a 3: 1. you cant tell what is coming next wave, so have fun switching your towers in the middle of a wave while the enemies fly/walk to your base because you dont get told. 2. the switching mechanic is pretty dumb, you might as well make all towers attack both ground/air because the cost to switch costs almost nothing, but maybe some patience because of reason number 1.
VERY easy, pro tip: buy houses as soon as they appear then sell them when their price stops rising. oh wait, oops i think i just told everybody how to win, oh well, have a nice day
