Koppy went through many changes, every look with its own personality!

It all started with a prototype Scratch game in 2022, now we're in 2025 with a Gameboy game on its Beta/Demo phase!

Read article to know more about every design and each prototype!

Before doing the other sketches from 2023, there's this earlier sketch of one of Koppy's first ever designs.

He has different socks, and is wearing boxing gloves! He also had a pocket in his own body like actual kangaroos.

More animations! This time each frame being actually fully animated.

The parts on the sketch were simply moved around to make a flying animation, and then made the lineart individually on each frame (which is why the volumes are a bit inconsistent lol).

Name change! Kumper Socks is now Koppy Kopsocks.

This name change was made for a particular reason (the same reason as why Pac-Man didn't stick to Puck-man).

The logo will be updated later.

(The 0.4.0 build with the rebrand is now avaliable!)

SWIRL DRAGON

Kumper is now back in development!

It's been months since I haven't worked on this game, but now I picked up on this again and actually reworked everything from zero just yesterday. This is the progress so far.

This build is now playable too!

Koppy wants some #candy for his bowl!

Trick or treat isn't really practiced here, instead we have a knock off (i believe it was actually way before trick or treat? idk) where kids in 1st November ask for BREAD instead of candy, "pão por deus" or something

New enemies: SPIDERS!

They get on the ceilling, and then they rapidly raise down to the floor! If they hit you from above, you get hurt, but if you jump on top of them, you'll defeat them and even get a jump boost - allowing for some cool platforming!

random fish stuff. inspired in koi fishes.

2023 KOPPY SKETCHES!!!

Old design I came up for Koppy. He always had his socks on his previous concepts, but this was the first time he got a shirt. I ended up making him wear both.

University in december is hell, this is all I can do for Koppy for now.
