Thanks for playing, and for recording yourself play! You're pretty good, although I'd recommend to slow down a bit next time haha!
"Are we able to view the remaining enemies / secrets on the level while playing the level? I couldn't see anything about this in the menu so assume not (yet?) :)"
Actually that's a feature I'm going to add in the next update. Right now the game only scans the map when the level starts so there's no way to see the stats on the world map, but I'm writing a script to automate it. So in addition to seeing the number of monsters/secrets/etc. on the pause menu, you'll be able to see the stats on a new level on the world map too.
