I liked it! Very innovative use of physics.

I wish there was a way for the player to recover if they lost all their lumbermills as the moment you lose all wood production, the game just stalls - you cannot get wood to build another lumbermill, so you have no choice but to wait for the waves to destroy you, and depending on how high you built, you spend more waves waiting for this to happen than the actual waves building. If there was a way to recover, such as a passive +1 Wood per wave if you have no lumbermills, that would add more tension to the game as you struggle to quickly rebuild back up, rather than just simply be forced to give up and watch a really slow death.

Another thing the game can benefit from is being able to see the height of the next wave so I can strategize in advance. That way, I can see how high my walls need to be and evaluate if I need another wall. In one of the waves I was relatively surprised when the wave got super high, and I felt my lumbermills were unfairly destroyed as I lost not due to having insufficient steel, but not having the information relayed to me to prepare for it.

Other than that, here are the various things I liked about the game:

• I liked how the sea level slowly rises.
• I liked how the buildings can stack on top of each other and change their graphics.
• I liked how the waves get taller and how they come in and can even break up into particles.
• I liked the transition from calm to stormy, along with the overall ambience and atmosphere.
• I liked the GIFs that explain the game mechanics.

Overall brilliant game with a unique concept that I had to give nothing less than 4 stars in every category. I ended the game with a floating house that managed to survive several waves xD

Cool game love it, love the artstyle and the graphics, relaxing and interesting!

Nice game! I really liked the strategy in resource management and building placement.

• Animated title screen is good.
• Music is pleasant.
• Graphics are top notch overall. Wave animation is good.
• Change of building graphics while building on top of another building is really cool! Would have been nice if this occurred when building below another building (after the one below got destroyed) as well.
• Very painful to see the buildings vanish upon touching water.
• Is it intended that nothing can be built on top of mines?
• Got upto about wave 10 in two attempts before the waves crashed my nice colony, and the remaining buildings were up in the air.

This is a really good game overall, and amazing for a jam entry. Kudos!

Really well done, congrats on the submission!
For context I played it for maybe 15-30 minutes, here's my feedbacks!
1. The ressources (metal)
I feel like metal/stone is very difficult to obtain once you don't have access to the base island (after few storms). It's mostly due to the fact that you can't stack other structures above the mines that makes it tricky. Basically it makes it so you can't go upward after you placed one *(I simply never found a way :P ). Maybe making it stackable could be done, but then it depends on your design too, this is talking from a player perspective ^^
2. The waves/Structures
I love the wave system, the visuals for them is beautiful and the system is easy to understand. The structures and bricks only have 1 "hp" from my understanding making it very damageable at each storm, you often don't have enough to rebuild them all making a trickier progression. Maybe having 1 more hp as "warning" to make it clear to the player that the structure will fall in the next storm if no protection is given. The wall have that system and I think it's very cool, maybe it could use the same? 
Overall, love the execution of the theme with the gameplay! Good job!!
