Thanks for playing and sharing your thoughts!
Could you take some time to record and send me this camera issue??
Also, the majority of sprites and tiles are from this tileset; it is free and under CC Attribution license. Other sprites were drawn on office paper sheets with a gel ink pen (I also have a micro pigment/archival inker — similar results and less messy). The grid was printed on an inkjet printer and made with my Papers on Demand (default settings with less intense lines).
