Brilliant, great to hear that you had a load of fun with our game and thanks for giving it a spin!
Regarding the speed upgrade, you're probably right that it could do with a cap. However we intentionally left it uncapped, as a sort of "double-edged sword", if you upgrade too much you'll have to live with being Speedy Gonzales for the rest of your run. (╯°□°）╯︵ ┻━┻
You completely hit the nail on our head with the camera, we didn't put enough time in jigging around with it to get it feeling just right. Definitely will improve that. Perhaps an unintentional sea sickness effect? 😅
