Oh, now I tried Toad's Mining Company. Again, overshooting longjumps is NOT FUN. Because of intense momentum, it's really hard to stop yourself from running off - and if you desperately hold Backwards direction, you risk running off backwards in the direction you came from! This is literally the same problem platforming has in Doom, but Doom is a shooter, not a platformer, so it can get away with it. Correcting your jumps is an absolutely basic skill in a platformer and it should be easily possible.
I can theoretically perfectly learn the correct length of a longjump and hit it every time, but:
- Should I need to?
- Assuming you really want me to do this, why isn't there a section that teaches me that?
- Assuming you really really want learning exact length of a longjump to be a thing, should it be part of potentially second level of the game?
- Hard fix - improve air control on longjump.
- Easy fix - you can simply add barriers (fences) on the backs around platforms that you have to longjump onto, and maybe make the platforms bigger, to make overshooting less of a threat. For platforms that you need to longjump onto, and then longjump further in the same direction as the first jump, you can add a small platform above the first platform, extending from the fence, like this:
Player longjumping will jump forward, bump into the barrier, then jump onto the fence-platform, and jump further.
Wooden platforms in Toad's Mining Company and the final jump in Colorful Jumping star in Color Block Meadow come to mind as platforms that could use such barriers.
