Just finished the game. Enjoyed it very much. Finished within 4 days.
As a person of moderate puzzle solving skills, heck, moderate smarts really if completely honest, this game had good difficulty: not a cakewalk, but not crushingly hard either.
I also enjoyed that it tutorialized all the features well. In my mind that's just another benchmark test in our times, and things like wall-of-text, or punishing the player with a mean learning curve are big no-noes.
The story is well written and told well; continuously in small bits, not impeding gameplay. Art work: also good, without hammering on the pixel art retro-chic too hard.
Would have enjoyed a more developed endgame, but the ending itself felt rewarding. Many points, will recommend.
Setting changes (audio volume) never actually saved for me between sessions (despite it saying 'saved'), so had to turn it down every time anew.
