My game had the same issue. If you ignored dialogue and just rushed to the end, it is a 5 minute game. If you take your time and really explore everything, it can end up being far over an hour. I sort of tried to fix it by including buffs. I later changed it to stacking buffs where every 10 minutes, you get a stronger buff applied to your party so that after 30 minutes, you can beat the game easily. I did forget to disable that buff from the harder difficulties though...
Viewing post in What was your greatest hurdle for this Jam?
Yes, I also have a couple of small problems that I didn't have time to fix in a hurry. But not critical.
Oh, and I remembered one more mega-complicated thing... This is to come up with a name for the game! I was close to the fact that the word "star" also got into the name of my game, like half of all participants :)
Yeah, I named my game following the same naming rule I use for the other contests of this type, but I was tempted to throw Star in there and call it a day. You have no idea how close I was to naming my game: "That one Touch The Star Game Contest Game That Used Star In the Name So Many Times That They Hit and Broke the Character Limit Because Of Their Obsession With Adding Stars To Their ******* Title"
