Hey, you are completely right and I do apologise. Although there is a little information on the page about the “in game photos”, it does not justify it enough to state that it is not the full art and I apologise for that.
As for the assets, I use GMS and therefor the assets are copied over from a master sprite sheet I use. It would seem this way is definitely not best for other engines, and as you state, non-artistic personnel.
I will change the description in this pack to state the difficulties you have found. I will also accept a refund if you can fingure out how to move forward with that as I am having no luck finding how to refund from a “sellers” persperctive, sadly.
Thank you for reaching out. It is truly appreciated and again, I am sorry for the confusion and difficulties caused here!
