Is there a possibility of us getting single level runs?

If you would like to submit your IL's you can do that on TSC, a website made for Level runs of sonic games http://www.soniccenter.org/rankings/sonic_colors_ds

Thanks

It's not an issue or anything, but I am curious. Why are IL runs on TSC and not on the Speedrun.com page?

Historical reasons more or less, the other Rush games have made moves to SRC so given enough interest that change and migration could be applied here
