What if... we had a "Freeze Time" option in which you can spend Tachyons to allow yourself to continue progressing without time passing. This would be a "Single Use" Purchase (IDK how many Tachyons doe).
It's almost impossble to get the last minute in the "slacking" even though it shows 0 mins slacking, the final minute cannot be acheived even by GSD 1200 (according to chat).
