Forsaken milestones

Roblox forsaken has multiple different characters, and each character has milestones, which take hours and hours to get milestone 4 (level 100), i have 8 days of playtime and i only have one milestone 4 character. and just like the lemonade stand challenge, you can make it so there are multiple challenges for one thing, since there are 4 milestones, but milestone 1 is easy to get so probably like 50 coins, 100 coins for milestone 2, 100 coins for milestone 3, and 200 for milestone 4, but you would need challenges for each character, which is fine, but for the milestones that would take a while, instead, you should also add something to the challenges page, you can hide the milestones and just put the first milestone, once you complete the first one, it changes to the next one, or an access thing like the skill tree, so there arent too many challenges.
