Just a quick note in case you're missing your awesome highscore for one of the levels: Apparently we've had a bug that wrote the overall highscore into the level highscore. I'm currently investigating this and if this was a bug in Alpha 53, it will probably also be in Alpha 54 (which I have just pushed live a few minutes ago - patch notes are on their way but it really wasn't much except fixing that annoying startup bug we've had). In that case, Alpha 54 will be online for only a very short time because this is an issue I feel needs to be fixed immediately.
One unfortunate thing about this is that Steam only keeps the highest score, so if this bug overwrote your actual highscore (which it most likely did), this information will be lost. The good news is that I can figure out the actual highscores by reviewing the track highscores (each level highscore also has its highscore of the track that the level highscore was achieved with). So I won't delete any "real" level highscores.
Apologies for the inconvenience this may have caused!
