Thank you for playing and for the feedback! Adjusting the primary attack's visbility is on my to-do list.
Regarding AlterEgo - the mode is definitely not for the faint of heart haha. The positions of enemy spawns are mostly the same as Standard Mode, with only the enemy amount and screen-wide formations adjusted to be humanly possible to bypass. It's a mode that requires a fair amount of skill as well as remembering which enemies spawn where. I recommend playing AlterEgo only if you've already had enough of the other modes, or are looking for a really really tough, but 100% beatable challenge ^^
