well you'll hit a gacha-wall eventually, some of the puzzles are character-locked, and you can't play it forever daily your progress is locked to 3 (simple) bossfights a day you'll have to grind for days to upgrade your characters.
if you just want something to do while watching streams etc. daily for 1-2 hours and look at some nice asses (there's instructions to unable the characters getting transparent while looking up), this should be your game, yea. Depending on who you pull.
If you're more on the loli side, Mona and Fishl are top pulls as well as Barbara, otherwise Amber and Jean as well as Lisa can make quite a lewd noise while featuring great backsides. The earth-slut is also quite hot. People also say Kek-king but I don't have her.
