Okay, so I got a lot to get through in this review, so this may be another long read. However, I feel this game deserves it because I really think you got something good going here, and so I want to make sure that I am as thorough as I can be on here.
I always like to start positive, so that's where I'm going to begin. This is a phenomenal idea! Making games for the disabled should be (I feel) a bigger deal. There's a lot of untapped avenues that could be explored, and I think this game concept you came up with is a fantastic example. I didn't get to play through the whole thing this time, but I explored enough to get a pretty good understanding of what you were trying to accomplish and what the game feel was like.
In real life, I love cooking, so cooking games do appeal to me quite a bit. My favorite game in Game & Watch Gallery 2 for the Gameboy was "Chef". As such, when I saw this game was going to be a cooking game for the visually impaired, I was immediately intrigued. I absolutely love this, you two. I really believe you got something here if you can manage to polish up a few things which I will discuss here in a minute.
I was surprised by the sheer size of what was available as I know you all made this for a game jam. Lots of different food options and cooking methods, and having thirty recipes is pretty solid. I also really appreciate you having a timer sound for counting seconds. That was a very smart design choice.
For English not being your native language, you did a really good job. I didn't find myself having any problems understanding what you two were saying. Good job there!
Now, there was one major thing that I think you may want to consider doing. I know it won't be fun and will require a lot more work and recording, but I strongly suggest creating an optional tutorial recipe that walks you through each and every step. You did a really good job writing the instructions on your game page, and going over them briefly in the "How To Play" section of the title menu. However, it's a bit of an information overload, and I found myself forgetting the instructions once I started my first recipe. It took me about four different failed attempts before it all clicked.
The best way to combat this would be to have one, maybe two recipes that you walk the player through. Tell them each and every step as they perform said step and offer them the option to replay the tutorial if they need to go over it one more time. You can make it optional by asking the player when they start a new game if they would like to play the tutorial before beginning.
Overall, I really loved this game idea, and I really hope you decide to do more with it. I could see a story mode done for this where you play as someone starting a new career as a chef and maybe include some visual novel (without the visual aspect) elements to add intrigue. You could include time limits for completing dishes, while also having multiple orders being made in the later, harder levels. All of that was just tossing some ideas out there. It's your game, so it's totally up to you, but it's something to think about. I really do believe you could turn this into something amazing for the visually impaired. Anyway, my brain has melted a bit, so I'm going to wrap this up here. However, if you would like to discuss this more with me, you know where to find me. :)
