Dang, we thought it would add padding for resolutions like that instead of cutting off text. We'll look into that.
The "double rate meteors" is the only way either of us have managed to get scores as high as 10k+ while playtesting. You really need the "slow meteor chain" upgrade too, but those two combined with enough luck and quick reflexes, the increased number of meteors leads to longer chains, and longer chains lead to exponential score growth.
But it's definitely a high risk, high reward upgrade to pick. Thanks for your comment, and thanks for playing!
