Pros and cons are down below) Check out the first minutes of the game here if you want to (but don't forget to like and sub ;))
Advantages:1. Game mechanics are very interesting. At first it was a bit confusing but after the tutorial, I started enjoying them a lot. I think it's original and creative. I loved both exploration mechanics and fighting. Great job!
2. The art syle is unique and lovable. Creates a very cool ambiance!
3. The game has a weird appeal to it. And by weird I mean that I can't even figure out what exactly draws me, but I just want to play more. It's just so much fun. I mean, as I'm writing this, I'm thinking when I'll be able to play more. It's very cool!
4. Also, liked the story and the amount of endings (haven't reached any of them yet, though). I like that there are missable notes that can reveal more about the story or characters.
Disadvantages:
1. It would be a nice touch if the items the player equips would affect the appearance of Marie. I think that would be neat, though I can imagine how much time it would take adding these details.
2. For me personally, hiding mechanics were the hardest to understand. I spend a lot of time in the tutorial trying to figure out what I was doing wrong. Turned out that I have to be mindful of slashes and type "close door n\". That made me thinking that the game would benefit a lot if the tutorial would have examples of the stuff you can write (like not in the brackets like they are now but in a text so even dumb-dumbs like me would figure it out). Something like that: "you can also hide in the game. In order to do that close the door behind you. For example, the command "close the door s\" would close a particular door on your south but the rest would stay open, be mindful of that." I know that this suggestion might seem funny but I really had a hard time and more examples would be very helpful. You can even add them in a different part of the tutorial just for people like me.
3. Also a list of verbs that a player can use would be really helpful at the start. Maybe like in the different window on the right when one can see equipment. Or maybe it was there then it would be nice to point it out in the tutorial that a player has it because in that case I missed it. It would be helpful a lot because at some point I forgot about going "up" and "down" the stairs ans tried to "ascend" and "descend".
Overall:
The game is a bit confusing so the tutorial is obligatory. But after that, it's just so much fun to play! I definitely recommend it and I'll definitely play more. I rate it 5/5. It's interesting and original and weirdly addictive. Great job, devs!
Hope my feedback was useful!
