I spent 3-and-a-half months working on sloped tiles using height-maps. I’m using LÖVE to develop my game in, and Tiled to make the maps.
Now I’ve started on my game, I don’t want to give too much away right now, but my main character is a Fox named Flash and he has to (surprise) rescue his girlfriend from a tower.
The game will be speed based. In this video I’ve just created some quickie temp graphics to give me visual feedback when you punch your enemies. So I will implement enemies next.
