Level designer here. Regarding the arrow tiles, there's a missing animation that would have helped the player better understand what they did (they turned the dice 90°) but admittedly the tutorial level that introduces them does a pretty poor job at teaching/explaining the mechanic to the player. We're 100% planning on remaking that level and some other parts of the game too for when the voting will be over and we're finally able to update it~
Thank you so much for the kind words! <3
