Quick maths! Sometimes I would be on top of an item but not pick it up. And on the results screen, there were some items that weren't green, yellow or red, which was confusing. A good concept in need of some polish.

Yeah, another player reported that the item pick up range is really tight, lol. I should have added an indicator telling you if you'd pick up an item if you press space bar now.
About item having no color at the score screen, it means that you didn't pick up the item nor is it in the optimal solution. I'll have to find a way to make it less confusing, lol.
