The visuals for this game are on point! I love the color palette, the pixel art, and just the overall look of this. The vibe you have going on perfectly encapsulates your mechanical theme.
I will say that I did run into issues understanding how to best navigate and tackle problems that happened to the dam. The booklet of instructions was a bit intimidating; I even ended up causing a bug where every time I restarted the game, my flood levels would just rise in seconds. It probably sounds dumb, but maybe having like a quick step-by-step highlighting what parts to hit for early levels might help better teach players unfamiliar with these types of games.
Regardless, good stuff!
