This is great thank you so much for the feedback. Sounds like I have some work to do. I hope that I can fix these issues in future updates.
Sorry about having no content on the 'How to play' screen been struggling with the UI system it's still a work in progress. I will make sure to get instructions there asap.
The beginning speed is something I am trying to balance. You can increase it by adding additional thrusters once you unlock them. Parts currently can be unlocked after you HyperJump to another planet. This and other parts of the game are a bit too hidden at the moment open to suggestions on how to make those objectives clearer. Obviously a how to play would help a lot in this regard.
The graphics unfortunately are blocky on purpose. I hope that I can upgrade them and make them much more asthetically pleasing. I have not played too much with color balance yet or graphic effects.
Check out future updates and be sure to post any more feedback.
