Hello there!
I am so glad and honored that you played this small demo through. Also thank you for your kind feedback, you're a gentleman and a schoolar. :)
Unfortunately at least for now, this project is on a hold, but I also think that it has enough pontential to push forward with. The difficulty spike is true, so I even have to nerf the second level more (it was harder), or just move it to 3rd or 4th.
The glitch was found and fixed, and I updated that a couple of hours later. It was a dumb bug, I have a non visible switch so when the player walks into the boss' room, that door closes. Switches are also activated by projectiles, so when the big door opens, the two gargoyle's fireballs go through the level (they destroyed only if the player isn't in the same room as the projectile's starting room). The lower one activated the door so that's why it was closed. :D Then the failsafe kicked in which I implemented for an earlier bug, and that seems to glitch out the player for some reason... I also see I managed to left the boss's sweetspot visible. :D
May I ask how many runs did you make until you get to the boss? Or it was in one try? You took the platforming challenges very well! Your feedback is super appreciated, I am truly grateful.
Thank you again, I liked your video and subscribed. :) I will check your videos and playlists.
