Great game as always!
Not sure if I am just bad at it or is it too much luck based. In the sense that I often have runs that I know are going nowhere, but if I am lucky with the draw I might get an insane score. It is a bit frustrating to fill my deck with tiles with limited directions and not being able to do much about it. There are the destruction potions, but maybe there could be more options to customize the deck?
Some suggestions for quality of life improvement:
Viewable deck — clicking on the pile should show what tiles I already have accumulated. This would help when choosing new rewards and should be available from lvl 1 (not an upgrade). Some deckbuilder games even show the order in which the cards will be drawn, maybe that could be a relic?
Informative tooltips about the colors — this doesn't tell me what yellow and cyan do. The only information that I get is that you call the cyan color "blue" :) If I still need to memorize their functions, there is no need of a tooltip.
Make blank cards placeable (?)— not sure if not a bug, but during a boss fight I had (1) a khan gem place some blank tiles; (2) end without any playable options; (3) all tiles were collected, and a new hand was drawn; (4) I drew some blank tiles that couldn't be placed anywhere. Expected behavior: a) either don't add them to the deck or b) allow the player to place them next to tiles that don't point in that direction. (if there is a tile that points towards a direction, you shouldn't be allowed to place a blank tile there, because it would break the continuity of the line)
