Hey. Thanks for the kind words. I'll take a look at what's going on with those bugs. Thanks for letting me know!
Speedrunning the game is fun once you have completed it. There is a link in the itch description to the speedrun.com page if you want to check out videos of both my time and the current world record by ReFlex. For now, your best option is using LiveSplit to time your runs. I will see if I can implement an in-game timer at some stage.
