For anyone with questions about the challenges, try the wiki, it is the most helpful place, eventually, far later in the game, you are able to do all the challenges withing a minute
For challenge 3, when you have 79 boosters, it is possible to reset your boosters and buy factor x 2 > OP x 5 > -4 base when over 7 to make the challenge easier
The new update isn't perfect but it certainty has improvements. The new prestige system doesn't give enough points and there is too many low effect skills but the ability to level multiple skills is interesting. The Slav is way too high in magic and the hard turtles take away too much speed, maybe 2 or 3 speed subtracted per turtle. Maybe you could add custom challenges such as where users can develop a game set with self created monsters and stats that wouldn't have an effect on the main game. This game certainty has problems but it has far too many positives than negatives.
One thing you could do to fix the rifts is instead of the rift value doubling each time, just have the original value * the number of times you have rifted to fix it.
For the boss fight checkpoints, maybe you could make it so that when you hold down during the boss fights, you go back to the checkpoint instead of the island since when I tried to restart the mask fight, I endend up restarting everything.
