Epic finale, It would be amazing if you played "Poof's Killergarten 2 Next Time" which is direct sequel to this game yeah " Next Time" is part of game's title
It's actually cool that you got past the killergarten floor to the playground. It's unfortunate that camera v2 was a randomized boss there as it is the hardest.
I recommend you to play on easy mode, you can switch it by pulling the lever near the gate to killergarten and the orb should be green color after you do that
