Okay, the game is pretty good considering the effects of tsunamis and flooding, which are prominent problems related to climate change in Bangladesh. I think sometimes it's a bit hard to understand the direction of the water. Because the player is making decisions based on which direction the previous turn affected. That's how I was able to win anyway.
Overall, it's a pretty good game. I would suggest adding a directional flow symbol in the gameplay. That would add more interesting mechanics. Wind effects. The sound effect is really good already. The effect with the sound is already pretty good.
Adding more types of flood gates. Adding more complexities would make the gameplay better.
