The sudden red flash in the intro absolutely DESTROYED my eyes! It should be toned down, and it's an absolute must for this game to have a flashing lights warning.
As for the actual game - it's a fun shoot-em-up! The mechanics are on point, and fighting enemies is fun. The sound effects and music are also cool, and have that nice sci-fi-ish computer-ish flair to them.
The theme implementation is actually very creative. It's kind of surprising that in the community full of programmers there isn't all that many games about the 'void' programming terminology. A great idea!
Overall, good job!
