Alright, sorry for the delay, but here’s the concept design I made.
Top image is the menu screen, I styled it like an old-school arcade cabinet. Game title is on the top, with stats in the corner of the screen. On the right is the game selection, where you can scroll through games and tap them to select them
On the right, starting for the bottom and ascending, we have the shop, settings (gear icon), customization (paint brush), global stats (games won, coins/credits collected, etc. finally, daily/weekly mission and achievements.
We could also put some decoration on the left side, I didn’t know what to add so I left it blank.
Up top is system time and how much currency you have.
I figured we could probably make it so that so when you complete certain actions based on the game, you get credits, like getting 10 credits for every 5 pipes passed in flappy parrot, or 50 for winning a harder game.
Daily shop items are randomly chosen from a set every 24 hours or smth.
