Overall a high-quality rhythm game

Pros: Concept is interesting and original, stunning visuals, solid music selection (some great tracks are included), straightforward unlock system, fun gameplay, calibration wasn't a hassle, UI is easy to understand (for the most part), all base-game songs can be unlocked in a reasonable timeframe given enough dedication.

Cons (I'm going to go in-depth about these in the hopes that they could be improved on in the future):

[Unlocking is occasionally very tedious] - Unlocking can get very grindy when trying to unlock all three difficulties for every song, a good strategy is to unlock every Enjoy chart then go straight to Core and save Handzup for later, otherwise trying to obtain fuel in later stages will become a long and painful process.
[Untapped charting potential] - Even on Core difficulty, I still find the charts for pretty much every song (and yes, that includes En*****e) to be very easy. While playing, some parts in certain songs are very empty and could use some livening up, and sometimes drops can be underwhelming. Perhaps a fourth difficulty ranked above Core could be added to allow for extremely difficult charts.
[Vague difficulty rankings] - Charts are not rated on a numerical scale (from 1 to a maximum value). All charts are separated into 3 overall difficulties, Enjoy, Handzup, and Core. There's no indication on what charts are harder than others until you've played them all. Having a numerical scale for each chart as well as the 3 main categories helps players keep a frame of reference in terms of their skill level. Without it, players will have no idea how to prepare for a chart, and are left in the dark until they play it themselves.
[Poor placement of essential mid-game UI] - In my opinion, a mid-game user-interface for a rhythm game should have at least three key components: the score, the current combo, and the note judgements. When playing a song, the interface does contain all three of these things, but some of them don't show themselves as much as they should. The location of the score is perfectly fine, there's no need to change that, but placing the combo counter in the top-left corner is a poor choice. In my honest opinion, the combo counter should be placed where the player can see it at all times without having to divert their attention away from the main part of the screen. Having to look in the top left corner every time you want to check your combo could be distracting. Plus, a player attempting to FC a song might miss a note subconsciously and not even realize until after they've completed the song. If you want my recommendation for placement, perhaps you could place it in the center layered underneath the gameplay as a background element. As for the note judgements, as of right now it's just the color of the particle effect after tapping a note that signifies judgements. Maybe a small "Exact" could appear below a judgement bar after an Exact judgement is given, and so on.
[Vague Achievement Titles] - Sometimes I'll complete an achievement with a vague title (like RGB or Heartbeat) without even realizing, and have no idea what I did to get it. Maybe after completing an achievement like that, a small explanation could be given underneath its title in the Mission List section.
Overall, it's a very good rhythm game. It's not perfect, but it's very impressive. A few small things could be changed to make this game much better.

Rating: 4.5 out of 5.

Keep up the great work, and I can't wait to see more from you guys soon!

Developer Response ,

Thank you for your kind comment! Glad that you like our game in general :)

Regarding the unlocking system, we will be introducing new systems (e.g. bonus, buff etc.) in future to add some spices to the unlocking process;
For the mid-game UI, we actually have a SuperNova/Nova indicator at the right-hand side (1 lost for grey and 1 near/great for Silver; If you are on the SuperNova course that will remain Bronze) that could probably helps. Both showing the judgement words/combo numbers will in fact largely reduces visibility of the notes so we are still struggling on this part;
Regarding the wordings in mission section and difficulty rankings, we are definitely working to improve user experiences in future (while keeping some degree of uniqueness);
We totally agree that the charts are relatively easier right now, which aimed to help players to get used with the unique gameplay for now, but surely there will be an exciting inflation in future updates (and we are very good at doing this!)

Please stay tuned to our future updates!

Decent game but needs a few rhythm game staples

This game is overall pretty good. But the game desperately needs a numbering system to distinguish difficulty. Theres no way to determine which CORE difficulty is harder than the others without first playing them all. It also would benefit from harder chart designed overall which devs have stated they're working on.

It also would be nice to have a description of hidden achievements after unlocking them to know what you did.

Definitely needs worked on

Love the concept for the rhythm game
I was a little lost as to how the game worked at first, it needs directions how to use the game and where everything is. The pause feature during songs doesn’t work.

I’m sure I will find this game much better in the future. It’s already pretty cool.

Thanks for the comment!
We have some help instruction when you first start the game but we will try to add a few more to make sure every player knows where everything is. For now you may check the pause instruction here:
