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.
I am unsure if I drew this in 2022 or early 2023, I don't have the original file anymore to check. But I believe I drew this shortly after I released the first prototype "Kangoo Twins".
This concept is the closest I have to his first design. The actual first concept was drawn on my old tablet and I didn't save that one elsewhere so it's gone.
Medals... Stars... All over the place!
Added star collectibles! You can collect 3 of them in each level. (Also updated many screens to include stats on your medals and stars.)
Decorated the level + extended it just a tiny bit. Also added more bird enemies to balance with the many mice enemies in the level
Still going to make more changes to the level (all of those checkerboard tiles at the start might not be visually appealing)
Art that I made for my game during the #Devruary challenge!
I didn't got to post these directly to the game page, so here's a post with most of them there!
(Link to the original posts in the article )
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!
Development flow is at max speed! I'm confident that I'm finally getting closer at properly finishing working on the Demo!
- Remaking the 1st level (W.I.P)
- Repurposed medals to be the end goal for levels
- End level screen (W.I.P)
- And more! Read
Happy Halloween!
A new special update for Koppy Kopsocks is out! Enjoy this new halloween themed level for this holiday!
Some features that were in development will be added on the next update after halloween.
Remaking the first level! (Tile set not final)
Some of the feedback I got previously pointed out that the current level design felt too boring/empty, so now I'll remake the existing levels and change some aspects of the overall level design of the game.
Preview of the new 1st level: Now in vertical! (W.I.P)
If I put every single "1st level" I made into the game now then I'd have a full set of levels already 
Also did some changes to the jump mechanic and did a bunch of optimization.
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!)
VERTICAL LEVEL!
Here you have to go up instead to the sides to complete the level (the jump mechanics work much better in this level format!)
This might or might not replace the existing horizontal (normal) levels.
