just some random suggestions (Heavy Guns heaven):
‘Bowling Alley’ and ‘Radial Assault’ wave: can the enemies move faster at higher difficulty? i’ve seen that they are slow even at the highest difficulty.
‘Chickens n’ Chicks’ and ‘Flower Power’ wave: can the Heavy Guns (Gatling/Laser) sometimes appear at the center position of each group of enemies?
‘Egg Billiards’ wave: (you can choose or not)
-
can this wave be just for Gatling Gun? because of the name you know.
-
and also can the delay time between appearing and the first shot of Heavy Guns reduce at higher difficulty? because i’ve seen many players can kill 2 Heavy Guns when the wave just starts, making it easier than it should be at that difficulty.
-
also also can this wave have 6 Heavy Guns instead of 4 at >=100% difficulty? because we have 6 holes on a billiard table.
‘Side Entrance’ wave: can this wave sometimes have the Heavy Guns appear?
‘Wait Your Turn!’ wave: can four egg barriers each group sometimes change into Heavy Guns or Barriers lv4?, Heavy Guns/Barriers lv4 each group also ‘take turn’ to shoot before moving to new position.
‘Fibonachick’ wave: can the number of chickens spawning at each portal be like Fibonacci’s number sequence: 1-1-2-3-5-8-13-21 instead of just 3 chickens every time?, i just want some more hidden easter egg references relating to Fibonacci’s sequence, not just only the barriers’ shape.
‘Ramming Speed’ wave: can the wave’s speed increase a bit at higher difficulties to make it challenging?, i find the wave’s speed is the same no matter the different difficulties.
also can this change apply to ‘Rectangular Layout’ and ‘Quadrilateral Layout’ wave too? i’ve hardly seen minibosses spawned in those two waves.
and also apply to this
