Super cool game, but I encountered a few bugs. Please note that I played the web version.
- When getting hit by the downwards lunge attack by the first or third boss you can get pushed slightly into the ground, at which point you'll also become invincible (and invisible).
It makes it extremely easy to cheese the third boss since you can attack it but it can't attack you. - I flat out clipped through the ground a few times, but it was possible to get back to the map by jumping.
- During the escape sequence the game would gradually slow down until it became almost unplayable.
When I timed it the 200 in-game seconds translated into over eight minutes in real time.
