Really great game so far. I really loved Himatsubushi and this game is really cool as well.
At the time of writing this i've played for ~15-20 mins and got every single Red tablet!!
My biggest criticism so far is that, on said last one, it's really uncool to have the most luck-dependent minigame right before the end. But the total time being so high allows you to be lucky on one of the two memories which just allowed me to get it!
The Simon Says is good rhythm-game type difficulty, the Circle is very good fast calculation dependant.
Though i'd like for the memory one to be less luck-based though, especially for the bigger one. Maybe make it so that when you've found the 1st or 2nd crystal, the next one has to be touching it? Like if you have the first crystal in a top corner, the next one would have to be right next to it or under it.
Love the art as always and can't wait for the game to release! <3
Side note to other players: While definitly not easy, the game IS possible. Heart is pure short-term memory, and you can scroll to make it go waaaay faster which cuts your time by a lot. On the 5th tablet (dead center one) you can cheese your way through getting a red by resetting until you get lucky with the first minigame (i got a 5.6s on it which let me get red with 2s to spare even though i fumbled the last circle on which i got 6s).
My toughest challenge of all the tablets was the dead center one. I found the last one surprisingly feasible with a bit of luck, but otherwise with good reflexes they were all achievable. My biggest challenge overall was cutting enough time to be able to have 4-5 seconds times on the circles, because i'm not that good at pattern recognition. Since you're able to get under the required time for all the other challenges, you're able to be bad at the things you're bad at and focus on the rest, which i really liked.
