We are in front of a little gem. What a game!
As I have mentioned in other games, what I value most personally is when I see a new and original idea that ends up in the form of a fun game like this.
We are looking at multi-layered dungeons generated procedurally. What madness. I must admit that my mind blew a little at the moment I saw that I could dive "inwards."
Aesthetically, I really like it, both the color palette and the player-fish animations. The style of play is very original but without losing the essence of a roguelike. I understand that due to time constraints, sounds could not be added, but if you plan to finish the game in the future, some good relaxing music and sound effects will take this game to several levels up in detail.
In conclusion, I really liked it and was able to reach the maximum depth without being eaten by those crabs. I have a bit of thalassophobia, and the moment I saw strange fish, I had to turn back, haha. But in summary, I value this game very positively. Congratulations on the originality and the job well done.
