Slash Chord: Jam Version

Slash Chord: Jam Version (originally just Slash Chord) is a short game where you use the Space key to attack enemies that come from the side of the screen. However, you have to do it in tune with the music.

This is my first actual game, so I'd really appreciate any feedback!

This game was created for the Music Game Jam.

UPDATE:

There are two versions of the game. The first one (MusicGameJam version) is the version I uploaded for the game jam. This version is only available as an .exe file.

The second one (Post-MGJ version) is an updated version with a bunch of fixes and other tweaks here and there which was made way after the deadline. This version is in HTML5.
