I think for me, the fact that it is a Hollow Knight clone detracts from the experience.
The game itself isn't bad. The controls all feel pretty good, the music is nice(although it doesn't always fit the mood,) and the art is cool.
However, by comparing the game openly to Hollow Knight, you set yourself up to be the 'budget' version of something that already exists(and you picked one of the best games out there.)
At the same time, a large part of the draw of this game is that it's a Hollow Knight fan-game.
Still, despite the comparisons, it is a nice game.
