Yeah, I think 4 packages might actually be enough for your game, but you could also increase the number of packages if you plan to have several levels. So many ideas for updating the game, but rarely any game jam games get updates after the jam is over. I know that from experience with my games 🙈
Good, that we are on the same side with the floaty controls 👍
And yeah, I'm always taking a lot of time to give proper and constructive feedback for every game jam game I play. Unfortunately, that lowers the amount of games I can play and rate, but at least my comments are really helping other developers.
