A super big thank you from everyone at Ampersand! It makes us really happy to know that you and your friend enjoyed the game that much :D
The intensity can definitely sneak up on you! The idea was to try and replicate the feeling of bullet hell games, and other games similar to Super Hexagon - where the very fact that you're surviving and extra second, and inching closer towards a highscore, really gets the adrenaline pumping!
