There's something really familiar with this game...
Aqua Cube (also known as Aquacube) is a Doujin Game created by Mamoru Katagiri. This doujin game can be considered a clone of the Thunder Force games, specially Thunder Force V, since the gameplay, options menu, weapons, and sound effects are identical, and the doujin features a MIDI version of Thunder Force V's soundtrack.
NOTE: The MIDI soundtrack could sound different depending of the computer where the game is played. For example, the MIDI version of "Rising Blue Lightning" played in Stage 2 could have some instruments missing.
