I am reminded of the good old point and click adventure games I've played since I was young with this one. How nostalgic.
The art style really lends itself to its unique voice. The background design is really well done.
There are some issues though. Namely its the tried and true guessing which item works on what to progress through the plot can be a bit obtuse at times. And its difficult to figure out what's the right solution to all this.
And also, the color text may tell who's talking but I literally can't follow the conversation all that much because there's no good way to remember the names offhand. Since there's no namebox I don't even remember the names of the characters that are relevant after a short period of time. I only know its black jellifish with glaceon lookalike.
Also I don't really know where to go after I got all the treasures.
