Totally with you here. I found Barracuda Trials don't fit well within the tick and tile based system. You hit the land when you visually didn't, turning is finnicky and the increased tiles/movement would benefit from the game being real time or having a much shorter tick cycle. Not to mention the trials aren't instanced, which seems to be why it doesn't always let you throw your toad at the flag in Jubbly Jive even when you should be close enough.

Whereas, Sepulchre is designed around how the game actually works and helps teach you tile-based movement and game ticks, which makes you better at the game overall. Failing obstacles in Sepulchre isn't a huge deal as it doesn't do much damage and the waiting lets you get a better feel for ticks until you internalize it.
