Nice try although it doesn't meet the rules with regard to resolution of 64x64. Seems like a higher res just made blurry...perhaps it can be tweaked in GDevelop somehow?
I Just embed it in 640X640 but that does not change the fact it's been build in lowRes... The "upressing" is what makes it blurry.. I could change the Embed code.. but that way the full screen button would be in the way!!
