Can't believe you took my shtick with your macrow mode, you'll be hearing from my lawyers. Jokes aside, a really solid and polished match 3 game and is one of the only games where the 2 bit limitation doesn't just hurt the art and its clarity. There could be some improvements though, the difficulty scaling for the normal difficulty wasn't too good (I got to wave 26 and only died because I wanted to move on). At the start of the game, you have multiple skulls that you're trying to quickly get rid of, but as soon as you do, the difficulty falls greatly. I think a part of this is, unlike other match 3 games, you can rotate without it having to match. This means it is much easier to set up your board to make bombs and the alike. I not sure if forcing you to match every turn would be the solution but I think something to keep you matching would be. The calamity mode was a nice hard mode, though could be a bit unfair (as you probably noticed). I think it would benefit from having your board being empty of skulls at the start as a there are times when a skull is created lodged beside blocks and there's no way to win.
Overall, still a great game and I loved the combos I was able to do
