Way. Too. Difficult. This is the first game in this game jam I've played I'm not going to finish.
I'm clearly missing some kind of hidden mechanic strategy, but I've tried I think it was day 9 (first non-tutorial for torpedoes) like 4 times, I couldn't get through. It's just too much, and I can't imagine how much harder the levels are after that.
At first I was going to leave a comedic "Please for the love of god get me a new sub.", but genuinely, with the stress the game introduces I got extremely frustrated with the mechanics. Why isn't the button that drops things the exact same as the button that picks things up? You can only carry one thing anyway!
Please keep in mind that the player does not know what you know, the game will always be unfairly easier to the developer. Players don't know the hidden mechanics. They don't know if it's smarter to keep something burning, only to fix it later. Or if they should even bother with the torpedoes. And forcing them to go through it by trial and error (instead of a more direct UI, or not being able to repair anymore when something is at 100) is extremely disheartening to anyone who isn't a tryhard.
All that harsh critique aside. This game is flatout gorgeous, I enjoyed the story, and felt like it could've been taken further, though perhaps it was, I will never know, as I can't finish the game.
