Hmm, the thing is, I don't think that the controls are bad if you have the mouse, but playing it on laptops is hard. Surely, I would prefer if those cards could've been chosen with keyboard input (1, 2,3), and if it makes the game easier, then maybe they will have a delay before implementing/or just make the spaceship faster. BUT, maybe it was intentional to not use the keyboard, and in this case, I'm fine with that. I was still able to get over many obstacles normally.
Also, I found it strange that I could go to the left completely and keep going, although nothing was there. Probably, you know about that too and you were just restricted with time to block this zone somehow. But anyways, interesting game, and I liked the customization!
