If you want more outfits and hairstyles, you have to buy them using crystals. You can get 215 crystals daily through the daily quest which is really simple to complete. Daily quest has a 7/8 hours cooldown so there's a chance for you to get 430 crystals a day if you're desperate enough. You will also get crystals for defeating bosses in another mode that will only be available to you after a certain stage.
The nicer outfits/hairstyles aren't cheap though, some are over 4000 crystals so basically, you have to either play the game for a very very long time or spend real money to buy the crystals in game to get them.
As you progress through the stages, you get to unlock supporters who help you fight the monsters. They just help make defeating the monsters faster. You can upgrade them to level 10 using coins but after that, it's all crystals.
All in all, it's just like every idle merge game out there. If you have lots of time on your hands and you don't mind getting bored then this game is the perfect choice.
