Oi, wanted to buy your latest biome (the one with the spikes), but cannot (you disabled it somehow for it there + comment section?). Please make your biomes 16x16, 32x32 etc. .You do it for a weird 24x24, which 99% of other creators don't do and is not compatible when I want to mix and match them.
Also nobody is doing the "fake" retro tilesets like in these games:
Astalon: Tears of the Earth, Cathedral. So maybe that could be of interest to you. Keep up the good work, the backgrounds are all really dope!
Edit: Got the bundle (includes the spikey tileset), totally worth all your work!
