You have probably the best tutorial I've seen in this jam so far.
Extremely clear, to the point and great controls too. I'd appreciate it if you added it to the description of your game too, but honestly, it feels so good playing a game with a controls menu. =D
I don't think I was able to beat the game though. Is there an ending? If not, you may want to post your personal high score so others get to compare it with yours.
Pretty cool game too. I think I've played simpler version of thing a long time ago.
If there is anything else I'd change, is to increase the time in which the rocket is blinking and you are invencible. Just a tiny bit longer and that gives enough time for the player to reposition themselves on the screen.
