I've found that it's pretty much impossible to have any sort of nice looking graphics at all on a 1gb ram device. Like it's not even the issue of performance at all (40 fps is playable). It's that it crashes and burns the moment it tries to load a large sprite sheet, no error or anything, app just up and quits...
That's been my experience testing on a couple of samsung 1gb devices. Tried on a nexus with 2gb, runs perfect.
Construct 2 estimated ram requiremenent for my game is ~200mb. Is there any way to see an estimation for ram requirement per layout?
