Cycloid is a horizontal shooter with keyboard control and mouse-aim, and about four challenging levels. Or four totally trivial levels if you upgrade your weapons fully and keep them.
Originally it would have been a much more difficult game (or, equivalent difficulty to trying to play through without fully upgraded weapons), but at some point MMF, the game authoring tool I was using, decided to corrupt the source file. Corrupted source files in MMF can either break your game completely or lead to interesting and unpredictable glitched-out effects, as it did in this case: the missiles began emitting weirdly-behaving bullets rather than smoke trails as they were meant to. The effect was really cool so after restoring a backup I promptly implemented it as the game’s ultimate weapon.
The music is great since I just ripped it off from modarchive.
