This is a good attempt at a rhythm game. The rearrangements are all very good, and the charting is generally very solid. A very unfortunate thing is that the options menu seems to not be openable. That's a huge problem because volume settings are very important, as well as scroll speed. Personally, I found the speed to be too slow, which made some parts of the charts unreadable for me.
In particular, the end of the chorus for ChikuTaku when Ame sings "chiku no yugami", the outro of meconopsis, the intro/outro of reflect and "return to the sea a shark is all you'll ever be," and a lot of Non-Fiction where I had to hit notes on multiple directions right after one another. That last thing, however, would not be fixed if the scroll speed was faster. I know this probably would not have been doable in the time you had, but doing something like DDR or StepMania where the notes are color-coded based on when in the song they happen (quarter note, eighth note, etc.) would've been huge. I just didn't know how the notes were linked in the moment just by looking at them. Also when there's a lot of bloops on screen sometimes they hide each other which makes it a little harder to sight read. I personally would have also liked the road to be longer so there's more time to react to notes, but its fine as is.
The biggest thing about the game though is that there is not a combo counter and the judgement text is all the way in the top left corner. Having it be in the center below score, as well as maybe an indicator for if I was early or late would've been great. The score also doesn't reset between stages but tbh I'm not really playing rhythm games for score unless I'm tiering in an event lol.
Cool little rhythm game. Would love to see the rearrangements on YouTube, and if you get a combo counter in I might try to FC some of these charts.
