Took a while to understand the binary sorting of the museum, still would be more convenient to have them sorted as one, two, three leaves etc. Also the end game is a bit boring just on waiting the last science upgrades and last mutation (as I am assuming there will be a five leaf clover). Nice game overall.
@MartinS68 Actually if you look at the Upgrades, there on the top left corner is the Angel Upgrades. Under there you will find the remaining which will eventually get you to that 20%.
