I know the gameplay is super mediocre. It barely has anything special or unique. My goal this jam was to polish a lot to see how that affects jam scores and I think I did a pretty good job there.
I actually tried "holding space to charge up the jump" before settling on the current version. The only reason why I didn't go with that is that regular jumps felt incredibly awkward and delayed. The game is entirely beatable without this mechanic, it's just sort of an extra thing for people who want to try beating levels faster/with less objects.
