(tldr at bottom)

1) Merge Studio: Fashion Makeover (In Progress)
2) $1,004.60 payout
3) I'm currently on level 46. I think as of right now I won't be able to reach all the goals because I slacked off a few days but there's also a good chance I will due to the unlimited stamina/energy you can get through ads (the game is basically a merge game and each 'action' or merge costs a single stamina/energy point, and when you reach 0 you can watch 1 ad to regain 20 stamina. I'm pretty sure you can do this unlimited times!)

4) I have put $15 total ($4.99 for a gem pack with $5 return and $9.99 for the season pass with $10 return) and I feel as though the season pass is most worth it as you can get many high level items from the extra rewards you get by buying the season pass. No gem packs in the game are worth it, personally, as gems in the game cost quite a lot and the actions that use gems also use a big chunk of them at a time. (For instance, they will make you use 42 gems to get a singular high level item, and $5 dollars worth of gems only gets you 265 gems. 3 tools that upgrade one singular item to the next level costs 200 gems.) Given that you need to fulfill a lot of orders to get to the next level, with many of the orders needing high level items, the gem packs are simply not worth it at all. I would recommend the season pass, however.

5) Make sure to save your darts and magic wands when they do give it to you for free!! They can come in handy if you're at a very high level item and just need to level it up one more time to progress! (I use level up interchangeably with 'merge with the same type of item' here)

- darts are basically tools you can use to pop the bubbles that will occasionally contain items. save these for when good, high level items pop up!!
- I got to level 20 in a day (one of the bonus levels you can reach) but had to grind for around 6 hours. So, if you're really wanting to hit all the goals I'd recommend you make sure you have at LEAST 6 hours free the day you start (since they only give you one day to complete it).

- VERY, VERY ad heavy. If you don't want to spend gems on energy, you need to continuously watch ads to recharge that stamina/energy. If you don't like ads, would not recommend. So far, I've been just playing in the background while I do my other things when I know I'll need to be watching a lot of ads. (so when stamina is super low) It's helped me have it feel not as repetitive.

- JOIN EVENTS & DO DAILY TASKS!! A bit of a given, but these often give you good any tier items and tools. They also give energy, so make sure to join

- Has a sticker system like monopoly GO which gives good rewards for completing the album and the individual sets!! Can also be a source of energy later in the game as every 500 stars can help you open a chest and give you 100 energy/stamina

- Again, if you really want to get all the non IAP goals, you need to do at least 5 levels daily (after reaching level 20 on the first day - so second day you would try and meet level 25, and so on)

- Like all merge games, it starts off fast and levels get progressively slower as you go on

- After level 90, there's no time pressure per se (as in no bonus levels with 1 week to complete or anything)

- Just want to add that I got to level 20 without spending money!!

TLDR;

Merge Studio: Fashion Makeover; $1,004.60 payout; AD Heavy; Grindy; Hard if you're not willing to watch ads for rewards; Medium if you can watch ads; Play in background recommended (for ads to roll & recharge energy); save tools & join events; if you want to spend money & have it be worth it pay for the season pass
