I like the vibe that this game is going for - the art style is pretty neat, and I love a good bit of Bosca Ceoil music when I hear it. :p
I will say that even after reading the instructions on the game's start-up page, I was still pretty confused about what I was actually supposed to do. Eventually, I got in the rocket, and was just able to blast off and keep going until it said I'd won. Maybe I was just being a bit of a smooth brain, but I was pretty unsure of what to do from start to finish. More visual clarity on what could be interacted with - and in what way - would go far.
Overall, neat lil game!
