To get Scylez's next date, after scene 2 you select to hang out with scylez to get his first date. If you do this then during scene 9, the game night, let Blinki choose the food. This will cause Scylez to show up the next day and offer another date ^^
And to get more scenes in the minigame you'll just have to keep getting the heart meter to full ^^
Thanks for the kind words and support! I'm glad you're enjoying the game! :D
