Short update, I’ve been a bit busy so haven’t had much time to spend on this. But here we go:
Added pipe-blocks
Fixed collision detection, so Mario can now land on blocks
Improved scrolling a bit (and added vertical scrolling as well)
The game is starting to feel quite smooth now
Next I’ll be adding even more block types and see if I can re-create the map from World 1-1 … might also take a look at adding some Goombas and other enemies!
