Maybe it's just me, but I think the Target Range speed is set WAY too high; I can't even get a combo of 2, let alone multiple hits. Maybe it's fine for playtesters, but for an "idle" RPG, the difficulty level is stupid-high.
First a splashscreen! Start with a "THE GAME THAT KONG BUILT" splash, then a basic menu: "Start", "Options", "Difficulty", "Credits". I also propose that the "Credits" section will contain the usernames of whoever gets their ideas selected, for posterity.
Huh. Got all the characters, ran through again... Still got the "But you need all the characters to REALLY win..." screen like every other time.
Dude, would it be so hard to add a "NOW YOU REALLY WIN" screen for completionists after they put in all the work to get to 314? It kinda screams "Yeah, I didn't really think my game was engaging enough to really get you to the end, so I didn't bother.". That sucks.
