It would be pretty useful to know what devices can't run Construct games well. As of now, there are 8933 devices that my Android app supports in the Play Store. With no way to test them, an exclusion list would be nice.
However, I noticed on export options that you can restrict by OS. On the assumption that older devices are less likely to run C3 games well (for example, my son's S4 gets pretty low fps on my pixel platformer) perhaps it might be viable to restrict according to OS?
