Smudgy (low-res) graphics in Quell Free compared to Quell

Hello again,

I have Huawei Ascend G300 (stock Android 2.3) with WVGA display and when I compare Quell (the old, paid version) and Quell Free, the graphics of the latter looks like it was using lower resolution (HVGA, maybe) and it was just simply extrapolated for the WVGA resolution. Quell looks much clearer. (Unfortunately I can't make a screenshot on my phone.)
Also the menu in Quell Free (Play, Options, Progress, Back etc.) looks worse than in Quell.
