Can I do this?

I’m considering to use

• Unity
• Photoshop
• Inkscape
• sfxr
• Bosca Ceoil
• Google fonts
• Wacom drawing pad
• massive amounts of coffee
• a beer when pressing build button

Yes, I have an idea after 3,5 hours of brainstorming. It is time to build a prototype. Still no clue about the game’s final goal.
