What a detailed and thoughtful comment! You are very much correct that the balance needs work; the enemy spawning was done in the last 2 hours so I cut some corners and did not have time to balance haha. My original vision if I had time was to have the larger numbers be something like 5+ so there's room for different choices. First thing I would do for a patch is definitely to cut the amount of 7-8-9 and X-Y-Z. Thanks again for enjoying the game!
