in terms of art: i think you could improve the game’s aesthetics by ensuring elements have a constant pixel size. the wagon and the tree match up pretty well, but the leaves and circles feel very out of place in comparison
on gameplay: if you manage to survive the first couple seconds of transitioning from mouse to keyboard, it’s pretty much impossible to lose. making things faster as time goes on or reducing the leaf:circle ratio might make the game feel better. it would also be great to match the spawn height to the height of the leaves: it’s great on the left and right sides, but looks a bit off in the middle where things just spawn in air. (also you can fall out of the map and there’s no way to restart from there)
a more minor note: the music is nice, but it loops a bit oddly
