At the moment, the highest resolution image you can upload for one 'block' is 32x32 pixels. This means the resolution for a game with a 16:9 ratio will be 512x288 pixels. Compared to 1280x720, the minimum standard for today's phones, and the resolution is pretty awful. It gets even worse when you compare it to 1980x1080 and 4096x2160, both becoming increasingly popular today for both mobile devices and desktops.
This is only thing really keeping me from using Flowlab seriously. The resolution should be changeable somewhere, or at least use 720p as default.
I feel (especially now that saving is possible with Flowlab), if higher resolutions were supported, it would become much more viable for producing apps and games.
Thanks for reading!
