I had no idea what I was in for - this was so cool to play through! The presentation of space was really intriguing and playing with different tile combinations was fun. I have to admit though that I did need to consult the walkthrough for maybe about a third of the unlockable tiles? It was a bit hard to tell what some of the combinations could be, though I really like that you're rewarded with information if you manage to imagine the right combinations - fits the mechanics really well! Also that aurora skybox coming in after being surrounded by nothing... so beautiful... Really cool game!
