I'm really glad you enjoyed it. I noticed the easy difficulty curve as well after releasing, and was quite sad it wasn't challenging enough near the end. It was for the best as changing any of the variables I had for difficulty/scoring, without testing, would probably make the game unplayable. The Q has a short cooldown (2 seconds) and you can't use it in animation, to avoid being spammed, as it was even easier then. The game's balance lives on the edge, and it felt either way too easy or way too hard. With some more time, I could have added a better end game.
Thanks for the feedback!
