100% Achievements Impossible

[millercommamatt]

The only way to spend antimatter is to unlock stars. That's a finite amount and as a result one can only spend a finite amount and then earn 3 of 5 achievement points for antimatter production before you cap your antimatter storage and stop producing new antimatter.

Furthermore, it's impossible to store enough resources to buy more than about the 240th antimatter producer so you also can't get the achievement point for building 250 producers.

622 of 625 achievement points is the most you can get under the current game rules and mechanics.
