i really love this game, i think it has a lot going for it and a lot of the problems i have with it are more to do with technical issues than the actual design of the game itself.
i'll start with the things i love. the art style is eye-catching and incredible. it really suits the game and music. the design of this game is very lovable and charming. the music is very catchy and doesn't get old even when i end up replaying a level over and over again to get a better score. and act one of the story is genuinely fun to play through, the characters and dialogue are silly and enjoyable. i really did enjoy myself for the most part playing through story mode.
now the things that were not so fun. first of all, the game defaults to 1920x1080 every single time i open the game itself or the main menu, which gets annoying very fast. also it'd be nice if there were more resolution options but 1280x720 works fine. i played this with a wired switch pro controller through steam, and every time i opened up settings, it would switch it to xbox controller settings despite me always setting it to switch controller settings. it's a small problem but it also gets annoying fast. i can't speak for other control setting, but for the switch ones, on the menu, A and B icons are switched for some reason? they look and act fine during gameplay and the restart screen but just not in the menu for some reason.
some more issues i ran into that aren't really tech issues, the blue of the R and B (for switch) are really similar in gameplay and i often get them mixed up because of it. i struggle with the start of the second line in double lines because i don't have that lead in time like you do with singles. scoring i struggled to understand and even after reading the explanation page for it i still have a hard time wrapping my head around it. if there is a difference between easy and normal mode i could not point it out, even playing all the levels on easy, i struggle to get a score above C for every level.
honestly this game is very enjoyable and fun, even with the issues i've encountered. i look forward to eventually purchasing the full release however far down the line that may be. also for context, all these issues are as of V1.033. (sorry for the long comment, i really do love this game!!!)
