You might want to update it so that if you die on a wave, you just go to the next one. I accidentally discovered if you kill the boss and let the troops destroy the base, you can kill the boss again and get the rewards. If you do want to stick with repeating the wave, you could make it so you don't keep the money. I like a challenge but on some boss levels I kill the boss, get the rewards, but then the troops destroy my base. Then I have all this money to spend but its to easy now.
I think this is a lot better than the original. More upgrades and different gummies. One suggestion: tell the percentage of how much more of a chance we're getting, I don't know if im paying 15k for .5% or 5%. Still love your games juicy!
