Thanks a lot for the feedback! I will try and fix some of the stuff you mentioned in the near future
Regarding the questions:
- You can do with the outputs of the tool whatever you want, so commercial usage is totally fine, as long as you have the necessary rights for the original image.
- Credits are optional but always appreciated. If you want to add credits, feel free to credit in a way that suits you. Link to Itch would be nice, but a mention of the tool by name + my username would also be more then enough
I hope that answers your questions :) In case you ever release something where DitherMaster helped I would love to see it, so feel free to post about it here in the comments!
