I usually like all of com2us games, so it wasn't hard to instantly buy them when they first came out. a day or two later they got a price drop, then a couple of days or a week or two they went free. this seemed to occur a lot really fast so when homerun battle 2 was released, i just sat back and waited for it to drop. it wasn't long till it hit 99 cents. seemed like all their other releases drop fast or go free really quickly due to the fact that they are IAP crazy.
i wasn't surprised that this went from 1.99 to 99 cents to free all in a week. unfortunately for them that this just verifies to me to just not purchase any com2us games cause they'll either drop the price fast or go free and add IAP anyway.
