Hmm I don't know too much about texture filters, I'll definitely look into that. Any graphics in particular you felt was inconsistent? As for level 2, I can assure you that making a line like in Level 1 is downright impossible. Think carefully: how do you connect a continuous line without changing the constellation appearance? I've also updated the main page with hints about every level (supplement this hint with the one over there, and I'm sure you can get it :D ). Indeed, the difficulty was something hard to ease into, I had many wild ideas that couldn't be subtly introduced in the space of a roughly 10 minute game. Thanks a lot for playing, and I hope you'll give it a go again! :)

I agree, I also think the difficulty ramp-up to level 5 in particular was quite big, but I couldn't think of a better way to more gently introduce those creative mechanics. Glad you loved the game, and thanks a lot for playing!
