A quick suggestion, the Windows 95 look isn't well suited for game menus (takes an extra click or two for doing stuff, not that big of a deal.)
Here, I made a proof of concept with reference;

1 - Where the apps will go.
2 - An example app.
3 - Pages, for when the App store is somewhat bigger.
4 - Dock/quick launch bar. Self explanatory.
5 - Example apps in quick start.
