+Licar mod for making TAS (tool assisted speedruns). This is a simple mod that
+only adds one feature: instead of completely restarting a map, the restart key
+rather rewinds time a little back. This allows to retry any part of a map as
+many times as one desires. It also helps to slow down time in the settings.
