It's like if Super Paper Mario had random battles and far more puzzles. A storyline about love, love and apples. Cute and Adorable scenes and characters, and some dark moments towards the end!
The battle system is quite innovative. Using an aiming mechanic you can defeat foes, incapacitate them or use a simple SMT/Undertale style negotiation. What's praiseworthy is that pacifying enemies is intuitive. Such as tossing an apple into the open mouth of certain monsters can be more strategically viable than killing or incapaciting. Solving the issue in Undertale/Deltarune where the pacifist option is longer and clunkier.
Only flaw is really the areas overstay the welcome a bit. The self-contained scenario of each area is fairly low-key for the length it takes to beat them. With most of the significance being the symbolic links to the main storyline which is revealed later in the game.
Overall a very good indie game, well worth playing!
Given its free and you're interested enough to have read this far in, there isn't any reason not to give it a try.
