Really nice art, interesting game.
I think it would be better if the acceleration and deceleration were faster.
Having to always throw away a tool to pick up a different one is a bit clunky, it would be good if there was a tool bar to easily switch between them. But I guess carrying only one at a time is part of the challange. I seem to have trouble finding a dropped item on the ground more often than I'd like to admit. Maybe there could be a highlight to them or something.
Lastly, picking up stuff is a bit tricky coz it feels like you have to stand in a pretty specific spot.
