A fun implementation of the term "ship" in multiple ways!
This is a very SBIG game from the concept to the execution! Always fun to see references to previous SBIG entries, but this actually implemented some of the mechanics of those games too which was really cool!
The physics were janky and the boat bumped off everything imaginable, which is perfectly fitting for SBIG, but I managed to get through to the (non-existant) ending!
The added murals I think were definitely needed, my alternate suggestion would just be to have the controls on the side of the screen at all times, though imo that can be distracting (and I say that as someone who did such an implementation in his game).
I agree with the other comments saying the cannon enemies might be a little too accurate, but these things are hard to balance.
All the visuals and sounds in this game are great too btw, and love all the little dialogues, and the cover art is amazing. I could definitely see the mechanics of this being spun further with more characters.
Good job!
