Cosplay wave: add another cosplay but make its direction and starting position randomized not according to 1st one. And to make it not hit the player by accident add a danger zone and make it appear first in starting position like how it is with Cardinality of Four wave.
Also bring back these tweaks but starting from 125% difficulty:
Burgermeister™ 3000 boss: sometimes while hitting the boss it plays the whistle sound but no bread fall. Is there a chance bread go offscreen from the top or it just doesn’t fall everytime the sound plays?
Dive Bombers wave: increase bombers to 4 and make 2 appear at a time(from both sides) so wave doesn’t end quick.
Volcanic Eruption & Water Fountain waves: add a second phase to both waves and make alien container from Volcanic Eruption appear randomly in one of them.
The Claw Machine & Gashapon Machine waves: speed increase is needed for both waves because they are currently slow.
Chickens ‘n’ Chicks wave(zoomed out one): make center enemies be selected from miniboss tier like Flower Power wave.
Tribute wave: if Fester has the key the glow appears in the left/right side from the beginning of the wave.
Chequerboard Strut/Promenade, Pa-chick-o Machine & The Ice Cream Factory waves: increase enemy speed depending on difficulty.
Something I’d like to point out: In Double Team missions sometimes Superchick boss corners the player and spray the omnidirectional red bullets. This can gets much harder at dodging in Thanksgiving Edition because the tail of Turkey Superchick boss gets bigger and bullets doesn’t appear in front of the tail. I wonder if you can make the bullets appear in front of it?
Choo Choo! wave: I noticed that train wheels are not exactly running on the bottom of the screen. I wonder if the train should be lowered?
