A suggestion: With really popular idle games like Clicker Heroes and AdVenture Capitalist, you can do a soft reset that lets you restart from the beginning but with a bonus. Do that with this game. Call it the "Jelly Sacrifice" :D
It would be cool if over the boss zones (5, 10, 15, etc...) it showed how much DPS you need to be able to beat it if you don't have enough or it showed how much HP the boss had when the timer reaches 0
