Coin size not the issue, there's too many, it floods the game causing massive lag. need higher denominations of fuel, coins, and gems in order to spare the overload of objects on the screen. Lag gets so bad the guy won't even jump on command. Good game, great fun, but PLEASE fix this issue. This should have been a problem long since fixed every since Super Mario World Rom hacks because flooding the map was a common issue there as well.
motherships on normal have WAYYY too fast a spawn rate I don't have time to do anything by the time I've captured even my first planet they have 3 times my numbers and assaulting 3 planets at once I can't hope to compete with that
