*FOUND* There is a method for spending points quickly. Press Tab until the Yellow highlight is over the upgrade you'd like. Then hold down space bar. :)
I like it a lot. Perhaps an upgrade for "hitter" speed and/or power. As mentioned before, the bounds can be made very large, but once bigger than the screen, your bound to wait for it to reduce in size. Interesting concept though.
Too bad the clicking mechanism is f***ed for the people in the back row. You can't click anywhere where there's going to be a red bar, so you'll lose by the time you get to round 10.
Level 3 single-handedly ruins this game. This author has no concept of game design. Congratulations on making one of the worst levels of all time. Skip this POS.
