I've slept on it
No code, art or even scribblings on paper as yet, but I've given this some more thought overnight, and it'll definitely be a side on 2D platformer.I'm going to limit myself to a maximum of one evening drawing the artwork, and that evening will have to be tonight. During the last 48 hour competition I wasted pretty much all of my time drawing, and wasn't able to submit anything.
I've a good few ideas about how the levels will work, and how I can make them challenging, and I've also a mental plan of the coding which will be required, how the non-game side of things will look (title screen, high score table, instructions etc.) and how I'm going to handle the physics. I'll be coding this myself as I only need basic "arcade" level physics.
All things being well I should get three evenings to work on this, and I'm really looking forward to getting underway tonight.
