Firstly, I really like the concept behind this game! If games have ever used this idea before, I've sure as hell never seen it, and really enjoyed playing it, for the short time it lasted. However, with a great new concept needs to come clear instruction, to show the player just how to play and win the game. While it's not difficult to simply scroll down and read the instructions to figure out the aim, the player shouldn't have to do this - there should have been an ingame tutorial, for sure.
The graphics were fine; nothing more, nothing less. They didn't look particularly polished or fresh, but they weren't horrible. They didn't amaze, but they also didn't offend the eyes.
The music was pretty nice, with a techno beat going on in the background, immediately bringing to mind space and explosive action, which are two things the game indefinitely provided.
The controls worked well, allowing you to move around with ease, and the space bar serving as more than responsive as a means of exploding and re-incarnating as one of the previously exploded green spaceships.
I also really like the idea of a little story. While it wasn't presented in the best way imaginable, it was nice to have some form of context as to what you were doing and why, though the lack of a conclusive cutscene was a tad disappointing. Also, the hit detection on your character was unbelievably off! At times, I would narrowly escape a collision with a ship, only to explode regardless of the fact I had clearly dodged the spaceship!
In conclusion, the game was okay. The story was nice and the controls really helped to make it an enjoyable experience overall, though there was very little in the way of polish, and the lack of any REAL story was quite disappointing. Also, the biggest crime was the length! Four incredibly short levels? I recently appraised 'Yeah Jam Fury' for having a whopping 46 levels, with this game falling a whole 42 levels behind! So, if you make the game a whole lot longer, with better attention to detail, this fantastic idea could well be executed to its full potential. As it stands, though, this is a great idea, let down by a poor technical effort.
