I loved the presentation, but like others here I just couldn't get the force needed to move the ball more than a few pixels. I imagine it's either the lack of a tutorial or something with the browser (I'm using Edge) or even that the game isn't fullscreen. For some reason I just cannot get any significant vertical velocity. But I can comment on everything else. The visuals were great, seriously the art style looks really good. I noticed the dust particles too! I think the game design is good too, because I learned the main controls without any text telling me what to do. I just wish the game was easier to progress in. I did manage to collect that 1 high up star in level 2, the line seems to jump higher than the ball. Still, I get the constraints of a game jam, sometimes we can't get the result we want. Regardless it's clear that this game was made well, even if I'm encountering some kind of bug.
If you get a chance, I'd appreciate some honest feedback on my submission too!
