Thank you for your feedback! Yeah we aren't sure what happened but the in browser/HTML game was super dark, almost like it didn't bake our lighting! Highly recommend to download the windows (or Linux) version of the game and all those lighting issues should be fixed!
As for the character going off screen, sorry to hear that! With all these fixed camera perspectives, it was really hard to make sure every little bit was covered! If you do give our game another go (through the downloaded file), I would love if you could add a screenshot of where you disappeared into. If not, that's totally okay and we all still appreciate it for trying out our game! :D
