Spinvaders is an arcade game where players engage in a space invasion, reminiscent of classic arcade games.
The game levels increase in difficulty as you progress, with the aliens becoming faster in movement, increasing in numbers, and obtaining better bullets as they go. Spinvaders features a unique point multiplier mechanism based on your shot accuracy. For every hit, the point multiplier increases (up to a maximum of ten), while missed bullets decrease it. Upon reaching a multiplier of ten, you acquire the "super-gun", which is more powerful and destructive. The impact on aliens results in the release of shrapnel that is dangerous to other aliens. The hit aliens then burn down the screen's bottom, posing a threat to the player.
The game's controls are described on the startup screen and are relatively straightforward. In this test version, an undocumented feature is that pressing "J" allows you to jump to any level.
The updated version of the software includes significant improvements to sound effects with a new soundtrack, thanks to David Tweet. Spinvaders is now an open-source project hosted at the developer's website, and this version includes small enhancements and bug fixes.
