Hi.
The game works quite well, the gameplay is a bit reminiscent of F-Zero. The difficulty increases over the stages, and you'll likely need a few approaches to beat a new level. Every ship got a unique handling, and the amount of levels and ships is great.
As far as I can tell you mainly added content in the past few updates. I highly recommend to polish what you got now.
- Improve the UI: Add a possibility to restart the level and to advance without exiting the game/going back to the main menu. If possible, allow to rebind keys. Utterly important: Rework the ingame UI - the grey boxes with the font look dull and they disturb the overall look and feel.
- Embrace your graphic style: It looks cool, but the abstract style could work much better then it does atm. Reduce the details, especially on the ships and stuff like the little people you can see on the seat rows. The glitchy, minimal style is great, and it would be cool if you could extend on it. Consider to replace the textures with pure colors and to increase the contrasts even more. Add some acid by including flickering, color changing elements and so on.
- Polish the core game play: Allow to drive backwards. Reduce the time it takes to come back on the track again when you make a mistake by reducing the speed gimp - you can, on the other hand, increase the general speed of the race and increase the need to use the brake to get around curves (rebind the key either to space per default or allow rebinding). Maybe add a small, speed dependent delay when steering to simulate sliding.
- Add some bling-bling. A flag waving when finishing, a traffic light when the race begins, and other stuff that makes the gaming experience more vivid.
- The music is a weak spot atm. It isn't bad and goes in the right direction, but for this kind of game your music should groove the fuck out of you - in the case of F-ZERO the music made the whole game. There are some talented musicians out there who would surely be happy to contribute to a game, try to find them.
- Offer a demo that is a reduced current version instead of an outdated full version. People who want to test out your game before paying for it will have a wrong impression since the demo might include problems that you fixed in the current version.
Keep it up and this might become a damn good game.
