This feels smooth to play. I did have the music cut out on me periodically, unsure as to why. The audio overall was great and the sound effects felt nice for their respective actions (such as eating the black holes). I also like the little flourishes for the end of level, and how the snake keeps going behind the UI afterwards. Especially cute! As for the progression, it felt good in the first chapter of levels. It’s really easy to have them be either to easy, or jump in difficulty during the intro so I really appreciate that. Outside of the audio hiccups, my only concern would be with the undo and redo. They didn’t feel as intuitive to me, perhaps because I expect different mappings for a game than I would in a typical document or the browser. Unsure why, so that might just be a me things. UI navigation though is really nice. Although the styling feels a bit like it’s battling with the style of the game? It might be coloring or the flat colors against the starry background and texture of the snake. It also might just be my quibbling. Overall, it’s a smooth experience.
