1. does 4 colors mean, 4 colors on top of the 2 white and black non-colors? example: white, black, red, green, blue, yellow, would this be allowed?Nope. Think of it as 4 shades of the same colour. So if your colour scheme was say RED for example, you could have:
- BLACK
- DARK RED
- RED
- WHITE
And these would be your 4 colours.
2. can there be shades of these colors? say have red and play with saturation or luminosity?
Again, nope. Imagine if we took a screengrab of your game and put it in to photoshop then asked photoshop to count the colours in that screenshot. More than 4? Well, this would be outside the spirit of the Jam.
3. what's stopping us from starting developing the game today? how does this work exactly? do we need to start building the game when the jam starts? or can we gather resources and start developing on it right away and just have it submitted during the 10 days?
Start building your game when the Jam starts if you want to be part of the spirit of things. It's about pushing yourself to see what you can make in 10 days, that's the only real prize on offer here.
