Commander Keen 1: Marooned on Mars
Online version of Commander Keen 1: Marooned on Mars for PC DOS. Commander Keen is a series of video games developed by id Software in the early 1990s. The series focuses on the adventures of Billy Blaze, an 8-year old boy who travels through space and assumes the identity "Commander Keen". In Invasion of the Vorticons, the player can walk left and right on the screen, and jump to get on higher platforms. Some of these are semi-solid and can be jumped through from below. In the first game the player finds a pogo stick, which he can use for a continuous jump. This makes Keen harder to control, but allows the player to jump twice as high if he presses the jump button at the right moment. Keen keeps the pogo stick for the rest of the series...

IBM PC with MS-DOS
Online emulated version of Commander Keen 1: Marooned on Mars was originally developed for the IBM PC and compatible computers,
with MS DOS - Microsoft Disk Operating System. It is an OS for x86-based personal computers mostly developed by Microsoft and released in 1981 as PC DOS 1.0.
MS-DOS was targeted at Intel 8086 processors running on computer hardware using floppy disks to store and access not only the operating system, but application software and user data as well.
Progressive version releases delivered support for other mass storage media in ever greater sizes and formats, along with added feature support for newer processors
and rapidly evolving computer architectures. Ultimately, it was the key product in Microsoft's development from a programming language company to a diverse software
development firm, providing the company with essential revenue and marketing resources. It was also the underlying basic operating system on which early versions of Windows ran as a GUI.
