#Devruary Double tap to sprint.

It's very simple, but on the engine I'm using I took a month just to get it to work at all (then I got burned out), now I'm trying to make it work right and it's probably the most puzzling thing I've coded so far

History of the sprint mechanic in Koppy Kopsocks

This 1 mechanic has unbelievable amounts of lore

Old sprint mechanic

When I started working on Koppy Kopsocks (which at that time it had the old name "Kumper"), you only had to hold B to sprint, which it was something that the engine already did for you on default.

But as I finally started to get feedback on my game, many pointed out how unpractical it was to use the jump mechanic with the button when you also had to move with buttons (this was a big deal when you played with a D-pad, and I understood the struggle when I tried testing it with a controller), many recomended me to move the jump mechanic over to the B button, which it was kind of a conflict since you also used that button to sprint (I tested it out and having both mechanics on one button can be conflicting depending on what situation you're in).

Note that there's only the D-pad, A & B and the START & SELECT buttons.

I couldn't move the jump mechanic to the A button since it would replace normal jumping, the main reason I kept normal jumps when I had the special jump mechanic was just to keep the gameplay smooth (since you'd have to hold down for a bit just to jump over a small ledge, which it would disrupt the flow over small things).

So I ended up moving the jump mechanic to the B button and moving the sprint to the D-pad buttons as a double-tap event (just like in Kirby).

Double-tap sprint

When I first tried to implement it I tried to follow my same technique as I used to code when I made games on Scratch, but GB studio has many factors that makes scripting different (it's made specifically for Gameboy games so that's obvious), so I tried going to Reddit and found a post with a solution... except that it didn't work (and the comments also pointed it out) but there was no more activity.

So I dedicated weeks (I think it got to a full month) trying to figure out how to make a double tap script event, I rewrote the script many many times until I ended up reverting it to the old sprint code (hold B to sprint) just so I could release the "halloween update" on halloween.

After that I continued working on the new sprint code, I finally made it actually work but it was very unresponsive (and as I'm writting this post it still kinda is), so I spent more time trying to polish it until I burnt out and didn't work on the game for like 2 months until now.

Recently I came back to developing the game and I'm still trying to polish it, I already rewrote scripts many times just for it (which it just made it more unresponsive LMAAAOOOO)

I drew that doodle of Koppy in 27th october 2025! I might share all of my doodles & sketches of him someday.

How my game felt when I revisited its old versions: (Drew this with my right hand)

#Devruary Feedback on gameplay always comes first! It's helpful to make sure that your game is playable at all and to even tweak some elements to make it play even better.

Level title cards!

When you start a level, you are met with a title card instead of being teleported to the level right away.

For now it only says the name of the level, but I'm planning to add more stuff like indicating if you collected the medal there

I love ripping off very old game franchises from character to game mechanics without even knowing their existence

Just compare Koppy to this character ("Sparkster" I think) and the game mechanics in both games...

Yeah I'm def getting sued LOL

Mae Borowski is the main character of Night in the Woods! It's an adventure game that tells the story of her return to her hometown of Possum Springs. She was confirmed as canonically pan in a social media post by the game's creator Scott Benson.

My first shot at a webcomic! Starting simple and small.

Wanted to try adding a small feature, it ended up turning into a death battle against bugs that kept getting more bugged after every fix (it was like cutting hydra heads)

The game also crashed a few times... but it's stable now!

The MANY changes I did

The Knightling launches on August 28! Wishlist it now so you don't miss out: https://bit.ly/KnightlingSteam

To celebrate the game's impending release, we've added The Knightling Pack and The Knightling Community Pack back to the Shop!

I put the new feature to the test, and it plays horrendous

So I might only apply this new mechanic to only specific enemies in specific areas or a specific object just for this.

But I'll give another shot at making this play better, otherwise...
