After 7 consecutive work days, I am having the most unproductive slack-at-home Sunday today, eating popcorns and playing Bloon TD on my laptop. I have always been fascinated by games of strategy. I think the masterminds that designed these popular games are really geniuses - the game play objectives are always rather simple but so many creative elements can be incorporated into them to make it so satisfying to play.  I went back to playing Bloon TD again just to see how much the game has evolved since. There have been no change to the kind of towers and tiers upgrade (I have maxed out on all of them), however, there are a whole lot of new power upgrades and some new game types / maps. Most of the time I just stick to playing Battle Arena which is a two-player game that pits me up against other players...
