Yeah that's my biggest fear for the game tbh. With at least 4 confirmed side jobs (waitress, secretary, glory hole, & stripper) and 1 more apparently on the way, I'd hate to be stuck speed running the game to experience what I want when I can. Also the creators have said that they plan to implement a day limit of sorts at when the games finished (if I'm not mistaken an earlier progress report stated something like 100 day limit). BUT that being said, the last game (Melty's Quest) did have free roam for 1 of it's endings so I expect something like that for this.
Hm? You're already timed by Order penalties for 'Taking too long'(Thus you must be as swift as possible as is) and Order in itself(It's hard enough even to get it to 0 from the -numbers). Why would you add a hard time limit in addition?
The game isn't quite quick enough that multiple run-throughs feels good. Maybe I'm too new, but the feeling is you don't have time, you don't have money, you don't have cjoice(People speak of 'builds' but the battle system and rock-paper-scissors of the battle system along with the hard level limits severely limits what's even doable.)
I suppose what needs to be asked is 'how long is it expected to take to reach Level 5 and the ending(if any) in the first place? How many failures are expected/required? How many 'grinding/levelling' runs for certain passives/titles?
