Neat stuff. But can you scale the sprites up? If I have to use MV/MZ I must scale the resolution 3 times to see the battlers. Still, cool stuff and good luck.
If it ever happens that you wish for scaled up vers from a set the creator doesnt reply to (it happens), you can do it via Aseprite > export then specify the %. You should ONLY do so via multiples of 100's, as otherwise, you'll end up with uneven squares/pixels!
