I will say it’s possible to make games with phone’s and tablets, but its not easy.
Flowlab is really made to used with mouse and keyboard, so the ease of use for other devices is a LOT lower. Though I would like to see implementations in the future for a more mobile friendly experience.
I think I’ve seen Crimson mention somewhere he made Star Blast 2 mostly on his phone.
So at least it’s not blocking any requirements for touch, but I can understand the frustration.
