It's an interesting game, but the numbers have not been considered properly.
There needs to be a way to earn more genetic points. Even at max level it will take an hour and a half to reach Enlargement level 3, 2 months to reach level 4 and 160 years to reach level 5.
I suggest that every 10 Research Center levels earns a multiplicative x2 Genetic Point growth rate. Or the mushroom farm also has a way to generate Genetic Points. Or both.
Also, the scrolling on the mushroom farm should be fixed. It is very jerky.
Edit: There is no level 4, so no need for a 2 month or 160 year wait.
