Can you tell us what size the assets are? The character sizes and tile sizes?
I just installed the Pixel Proof - Honest Edition (PixelProof-0.4.0.exe). It installed fine, to the default directory, but when I ran it, I got a missing zlib1.dll error. I found the zlib1.dll on the internet and copied it to the PixelProof folder. This seemed to fix the problem. Just wanted to give you a heads up on this...I didn't see an email to send it to.
I'm using Windows 10 64 bit Home Edition. If you need more info just let me know :)
