This update's pretty simple (development slowed down due to new year), I made new levels for the Wrecks biome :
-7 new levels : One-way maze, Poison prow, Sea slug sanctuary, Venomous vale, Pick your poison, Treasure hunters, Toxic trap. Guess the new mechanics. Also some changes to Overgrown alley.
-Slight visual tweaks : adjusted submarine sprite being scaled up, darkened foreground sprites in Clam plains a bit.
-Slight level design tweaks.
That's it for now. Next, I might re-implement the shop in the demo to give a use for your hard-earned stars, or maybe I'll work on some bosses or on the visuals for the next biome.
