Hey, thanks for playing.
I'm unsure what the smearing you're talking about would be. Do you mean the monster under the water? It does fade in and out a little bit. Or are you talking about the cruise ship once it's broken? The cruise ship was just cut in half and rotated in GIMP, so that blurred it a little bit.
I'm happy you enjoyed the combat. The current crossbow implementation is a kinda wonky experiment, and I'm going to change it. Right now bolts are in the consumables, meaning you apply them same as you do healing.
All of the music in the game right now is free use, and will likely change in the future.
