I loved the game story and art style. A great and simple story together with awesome classic paintings.
I would suggest to put in the corner of each art a small box with the names of the painter and the painting (maybe even the date). This could make the game also feel like a stroll through a museum.
The gameplay is a great concept but I feel it needs some usability tweaks. My suggestions are:
- Make the current letter highlighted during the moment it can be pressed (with a bright color instead of being darkened with the rest of the word)
- Maybe add some faint audio feedback or visual effect in the lyrics together with the key press since is very hard to look at the right panel while tracking what to press next.
- If possible, make a difficulty curve controlling the amount of different keys needed for each song. The hardest parts are when you have too many different keys to press in a short succession (leave them to harder songs).
- An alternative can also be to change from letters to colors and limit them to 4. This could make the game easily compatible with controllers.
