A fun new take on "upgrade something you shoot"
I've gotten pretty used to games like Toss the Turtle and the recent Burrito Bison, so this completely different take on the same concept was a breath of fresh air.
One question: Is it supposed to be possible to buy more than three watermelons? The game wouldn't let me, even when I had the $25,000 I needed to afford a fourth. If three is intended to be the maximum, you should remove the BUY button or at least change its appearance when the stat is maxed out, and you certainly shouldn't list a price for an option beyond the maximum.
