Obviously a masterpiece. It took me a while to master the attacks, but once I did it becomes super satisfying to dodge them all. So far I've beaten normal and hard mode, perhaps one day I'll even conquer Monday itself... (prolly' not)
The one criticism I have is the pookie lasers. They are the hardest attack to dodge consistently IMO (yes, even more than Garfield gun), I'd suggest removing/tweaking the exploding AOEs that happen during that attack.
Again, a fabulous experience overall.
