Thank you so much for playing our little roller, and streaming it too! - We're looking into the lag / stuttering issues and have taken note of the camera position for future releases. Concerning the Level Length it is just that, Short should you be able to complete in about 3-4 minutes if you dash and jump your way through, long will make the "production / obstacle line" longer (6-8 minutes to complete using dash) and endless is truly that.
