Seems like there's a softlock after climbing the cliff on the beach,
there doesn't seem to be a level transition into the town.
Edit: not really sure if the lifeguard quest is broken or not either, going back starts his dialogue again and going up the cliff and losing the ticket doesn't do anything. You can go back down and back up the cliff like walking after the cutscene though.
Yeah, I was working on actually testing the maps for the first time right up until the last few minutes, and the island area got hit the hardest with uncaught bugs. The lifeguard bit was especially bad because I forgot to set progress switches AND drunkenly coded a bunch of ‘move right’ (back towards the last map) as ‘move left’ (and basically skip the checkpoint altogether, with no way to go back because of those switches that didn’t get set).
I do have a bugfixed build of the game that (hopefully) solves most of the major issues, although it probably needs a new save to work properly. However, it’s outside of the scope of this jam and it won’t be uploaded to the main itch page until after the review period has ended in a couple weeks or so.
