At first I was thinking 'Meh, another puzzle bobble clone', but then I saw that the next muffin isn't random and the game immediatly became a greatly satisfying tactical experience :) Now, it would be utterly awesome if you added 'blind mode' where you can't see what muffin the monkey holds (or without the monkey at all).
What the fuсk, clicking on introduction screen sends you to dev website, clicking on ad at the beginning sends you to dev website, clicking on ad AFTER THAT sends you to dev website... 1/5
Ah, good ol' Touhou... You've even ripped off deathbombs! :) My only complaint would be the lack of focus mode (hold shift = move slower), otherwise it's awesome.
I like the basic idea, but you screwed it up with fake difficulty - instead of bluntly increasing the pieces' size, you could try to make the player's life horrible by the normal tetromino, but chosen to be least useful to player.
