Hotfix: controller issues solved

Just a quick update, likely the last one before the jam deadline ends.

• Switching between players when playing with a controller, in solo mode, was broken. Fixed now.
• Starting a level from controller was also fixed. (Controllers used to work completely, but I last-minute improved the main menu yesterday, causing an unexpected regression.)
• If a level has no special egg types, that interface is hidden, to make your first impression of the game even simpler.
• Similarly, the second level has a lower maximum on egg types, to make sure you’re not hit with overwhelming randomness.

Thanks in advance for playing, Pandaqi
