The concept for this game is great and has potential but there are some concerns/issues I have.
-1: The tutorial was a bit hard to pickup especially on the shop part of the tutorial. I would consider visually showing what to do instead of text to better clarify to the player what they are doing.
-2: When you ship is stuck in a corner while the map is shrinking you can't do anything about it to save it. I would add a visual counter to show how many turns before the map shrinks just so the player doesn't get stuck in someplace where they cant turn (maybe allow them to partially be off the map).
-3: I might be wrong but this game could lead to some unfair rng issues and some uncountability to enemy attacks. (Aka an enemy guessing a spot that ends up hitting your ship and destroying an important equipment piece). You could make this a bit more fair by giving all ships a spare part they can hold onto when one of their ship parts gets destroyed or just having a shared inventory of replacement parts.
-4: I'm assuming there will be a way to buy more ships later on since losing an entire ship is very punishing with no other way to buy them in the shop.
I hope you will be able to address these issues for a future update or steam release since I believe these are easily fixable.
