I did do it myself ! It's the second time I try this art style, cause not only I think it looks cool, but it's also super efficient, specially when it comes to animation, which is important to get the most from the short duration of a gamejam (this game was made in 7 day for a Brackey's gamejam).
The first one I made with this art style was a narrative platformer called "Fast" that was also made for a 7 day gamejam.
