Yeah. I totally agree with you for the shop menu. We intended to add a lot more features, but unfortunately we ended up having to code a whole map renderer thing from scratch.
In terms of the boat thing, I keep getting that feedback and meaning to move the top fish down a bit, so sorry about that.
In terms of the bubble glitch, it was really hard to fix. As I said earlier, we had to make something to draw the map from scratch. We didn’t like pico8’s map thing since it could only be moved 8 pixels at a time, so every animation and map tile is a separate sprite that’s being drawn (there is a function for it and a table and stuff so it’s not like we’re drawing each sprite separately). Because of this, the bubble is drawn on a separate layer. The fix for this glitch would be to basically make the bubble part of the map, and I’m not sure how we would do that without re writing a lot of the code. We definitely have a lot to learn for our second jam when we do one.
