Thanks so much!!
And yeah, thanks for the feedback. I was planning to do it, but since for somereason I deecided to have the doors as a tile, and not an object, changing it after was extremly difficult and I couldn't implement it in time.. This time I'm fixing it by having the doors have a cool animation of opening up I hope, so you know which ones you've been through. (maybe an increased difficulty level could be you have o remember which doors you've been through...)
Thanks so much for taking the time and commenting, and for offering constructive feedback. It really means so much to me. I truly appreciate it!
