Bloons got my vote!
Indeed everything Bloons that I've played has been epic win. I mean it's been over a week since I played this the first time and I've come back and played it every day atleast once.
There are a few minor tweaks I'd like to suggest: graphics option would be great, around world 3 my laptop starts to lag a little on it and it is hard to keep Super in line with raining bloons. And also on that note maybe adding a WASD type control would be nice too, the touchpad can be fickle and I found myself going outside the game occasionally (especially after the game started to lag)
