Hop! 2D beta 16 : thank you, covid !

Hi, everyone !

Development has been sped up for this "post-covid" new release, which brings many new features : 6 new playable levels (world 6 is almost completed, the boss level is still to be built), some already integrated  but not playable ones (next worlds and secret worlds), better background musics sound quality, new mechanisms (hyper-trampolines, rotten fruit, optimized enemy code) and a lot of improvements (transition screens, game visual effects and animations, presentation details, massive debugging).

Enjoy !
