Really impressive metroidvania game for a jam - the map was surprisingly big. I got stuck under a moving platform at the end of the patience corridor on my first go (after getting the speed control too) so had to start again. Finished in 10:47 with all items but no secrets - I could see the other areas but had no idea how to get there. Having my mistakes played back to me was fun, really nicely done.
Shame about the controls not showing properly although even after reading the comment on the itch page I still couldn't figure out how speed control works. Was it left stick up/down and then press the same button you use to open doors?
