Hello, I finished a "descent" and the game has potential but there are some issues,
1. there is a LOT of text on my face the second I try to play, I tried to read but I was a little tired and skipped past it like a "normal" player would
2. the gameplay needs FEEL (feedback, sfx, vfx etc..), a good example you can look at is other games like candy crush, or Dragon Chess minigame from dota 2, just to give you an example, I was expecting explosions, fireworks etc... makinga 10x combo, but it did nothing, it felt the same as doing a 3x combo, also the enemy doesn't feel important, it could be attacking you on timer like the dragon chess, playing some animation or even talking a bit to distract with some puns.
3. I don't really understood the mechanics as I skipped the texts but with some symbols (I did notice something falling into the sigils but it's not enough for a player to understand it without a lenghty explanation) you could ease this, as I kinda got it on the go playing the game, and reading again your description you said "Enemies telegraph their next move", I didn't noticed it.
4. the "relics" felt a little disapointing, and I didn't really needed it to complete the first run
