I feel like the map button and the restart button should be ramapped on M and R, instead of C and P, there are hard to remeber and to press…
At first it wasn't much clear that i had to go on the words "play" and "instruction" on the menù because they blended with the stars and planets on the background…
Speaking of instructions, the game wasn't explained very well in my opinion, maybe a tutorial level would have be better for explaining the rules…
Last thing : i wish there was a method, o a mechanic to help me aim bettere where i want to go, going to one planet to another was hard to do and ofter frustrating when i failed
I hope this feeback can help you improve… I liked your game a lot, and i want it to be even better than it already is...
