(c.a.p.s is now discontinued) f press b for a different tower.r for reset,s for switch plane,space for crash time, and d for map change,c for codes,up arrow for shop. if your building disappears,just type the building u want for it to come back games has a money glitch so that's how I got 16610 dollars and 302 crashes so please don't abuse glitches cool updates get cool rewards like extra money for the 100 view update.
I just did it and c.a.p.s stands for crash a plane simulator If u using mobile mode.the other buttons are in settings. If you press building switch.type1 for the first towers, type 2 is another type of building, type 3 is ANOTHER type of building. Take no offense dudes
