Thanks! Yes, the first room is always the same, especially to show all the basic mechanics of the game. The difficulty only affects the speed of the wave. And absolutely all bananas are available ;) you just need to take a little risk)))
I will think about implementing these ideas and, perhaps, add another level of complexity and a static generation mode with have the end.
Oh, and by the way, the wave can't lag behind the player by more than 1 screen)))
