Been picking at The Big Catch Tacklebox off and on.

The Big Catch: Tacklebox on Steam

It's an interesting experience, I don't think I've played a platformer like this. (Note, I'm nowhere near done with this prologue.)

It asks for truly an extreme amount of precision from the player.

... but I don't hate it!

The controls are equally extremely tight and smooth.

It's difficult to get my simmering thoughts to congeal, but

It's kind of like a puzzle game but the puzzle is figuring out what angle to best approach this wall jump from, and spending twenty minutes working on the execution.

And then you pull it off and you're like fuck yeah!!

And then you see a shortcut you can activate like hell yes.

And then you see there's more to climb, oh shit.

I do greatly enjoy the design of it too. The characters have very good talky noises, it's got that faux PS1 look (just a little too clean to be PS1 proper)...

Will continue to pick away at this!

I could see speedrunners eating this game up

Oh absolutely, I bet the speedruns are going to be a treat to watch.
