Yeah, the dip to the far left next to the double jump crystal is impossible to get out of once you're in. Initially, we just had a gap there so if you fell through, you'd fall off the level too fast for the black hole to catch up and reset you. I intentionally made the pit a trap to artificially increase the playtime of the game a little since it was so short. And also to troll someone by making them squirm and panic as the hole inevitably consumes you and your progress on that section just before the goal. Very happy to hear I have at least one victim. >:)
Glad you enjoyed the concept. Thanks for playing!
