Thirding (?) this. The integration of gameplay elements into the story and the story itself are simply amazing. It is similar to Undertale, in that the gameplay is relatively shallow, but is paced perfectly with the story.
L cancelling is not a bug, it is an altered feature from smash 64, where it was called Z-cancelling and removed all of the lag from aerial attacks.
I also have a hard time to believe, that wavedashing is a bug, as they specificlly implemented a state transition for wavelanding (hitting the ground while in the airdodge animation), it is more a clever exploitation of this mechanic by jumping and immediatly airdodging into the ground, thus carrying over a whole lot of momentum.
The study explicitly states, that the problem went away for reddit, but this does not proof that the hate went away, it maybe just left reddit for another platform.
