I'm creating my first tilemaps.
In tiled, I did a 40 x 40 tile map at 128 x 128 px, and the map was 5120 x 5120 px big, versus the same 40 x 40 tile map at 32 x 32 px giving me 1280 x 1280 px in resolution. I'm making a web game from the typical HTML 5 (with canvas), JS, CSS3, and melonJS engine.
Does it matter if I make 32 x 32 px tiles vs 128 x 128 px? Will it affect performance?
