NOOOOOOOOOO I REACHED THE END AND THE GAME CRAAAAASHED T_T. I guess I died at the same time I reached the end? But don't worry, that's okay =).
That was REALLY addictive. Like, REALLY. I know the title is "Chrono Horizon", but honestly, you could have named it "How to masterfully manage your difficulty curve to create addiction" (but I guess that would have been less attractive =p).
I'm not really into SHMUPs but the whole gameloop completely got me. The graphics are really good, the music is nice and fitting, it lacks a little bit of impact sound (which is important in SHMUPs, because you're generally focused on your ship, so it gives you a feedback of your attacks ^^") but I'm just being picky here.
The game felt great, the game is great, and I might come back later to see the end =p. Congratulations!
