Very clever usage of the Egyptian mythology with this gamejam theme!
All make sense: each "Tetris" piece being a memory, "bad" memories being pieces hard to place, losing memory when losing a piece, the balance "measuring" the weight of these memories... Very very smart!
A bit nitpicking, but it would be great to have more "pure gameplay indicators":
- a clear number telling how many "life" we still have (instead of the feather degrading over the failures, which is very beautiful but not very self-explanatory)
- a counter telling how many pieces left before the end of the level
Anyway, very solid entry, well done!
