Thank you!
Agreed that the difficulty needs tuned a bit - a lot of the feedback is regarding that. I messed around with having the first round be a letter swap, the second round a vowel thing, and then the rules only combine in the third round so that it builds a little slower but I felt that it made the game a little too long.
I like the EA flip idea - making up garbage as I go is how I came up with most of the rules, haha. I had some worse ideas like turning all the letters upside down and having Caesar ciphers as rules.
