Sure, some games were written completely in C. I believe significant number were hybrids, performance sensitive parts in assembler and other code in C. Some games were prototyped in C and optimized afterwards. For example Amiga Turrican 2 required 33 MHz 68030 CPU during the development phase. Of course the final version ran fine on 7 MHz 68000 Amiga.
