Thank you!!
Aside from our discussing an initial basic theme, the way the art turned out is 100% Alix's wonderful ideas. I know the kind of stickers you're talking about and it's totally like that! The art definitely directly inspired the music/sfx too.
I actually had a crisis halfway through the jam where I couldn't get things to stay in time musically without mountains of extra tedious work... but when I took a step back and looked at Alix's art (and with some suggestions from her), it hit me that I should just make it a more ambient thing that doesn't need super precise timing. So her work kinda saved me from a breakdown, hahaha 😅
Regarding the skulls: yeah, there's definitely room for improvement. I'm not super pleased with the hitbox or the full randomness of how they spawn. It'd be nice to find a way to make the game a bit more challenging and a bit more fair at the same time.
Thanks again for playing and for all the kind words!
