Hey!
You make a very good point about not all Itch users using Unity. To be honest I'm not very familiar with other workflows outside of Unity's Sprite Shape and Ferr2D's plugin. But I'm absolutely willing to adapt my asset to accommodate more workflows / engines if I could get some guidance on what those requirements might be. In the meantime, I will look into creating a more "classical" tileset as you've mentioned. Thanks for this suggestion.
As for what I planned next for this asset. I currently have plans to add more decorations such as suits of armor, and bone piles. I also have ideas for a couple more traps. If you have any request for this set, feel free to send an email to me at hicartooncoffee@gmail.com
I do want to start increasing the amount of assets I release in 2021. I've learned a lot of cool stuff about making characters and I can't wait to share it with the community. New characters are coming soon :)
Thanks!
