so the spellcasting system is something i really like, i love seeing experimental stuff like this and that will always be cool to me. my main suggestions are two things: first of all, although having a limited resource to cast spells normally makes sense, i do think it would make sense in this case to not have a resource limit as the ability to cast spells is dependent on the completion of a minigame basically and thats enough already to limit the player, so adding an extra cost with the philosophers stones isn't necessary in my opinion. secondly i do think the player should NEED to cast a spell to get the game started, maybe by making illuminare necessary and have enemies come as a result of the darkness? i really like this game and its unique system, well done, with more spells, a more full gameplay loop and enhanced enemies i could see it working as a full release.
