S&Rush

by reg

100 levels, six level layouts and three worlds (ice, desert, city). Roughly an hour to clear. Gates add, subtract, multiply and divide your crowd. Some rows slide sideways. Hazards are not a tax, they are a reaction test: one hit costs you half your crowd, a second one ends the run. Enemy crowds charge you and cannot be walked around. A boss at the end of every level, with a health bar and a run-up you can read.
