I played with a touchpad, so enjoy this review with a grain of salt if that was not a developed-for way of playing. I liked concept and I think if there was a relatively long tutorial for explaining how things work this game could be great. I don't think I got the full experience, but I can see a lot of potential.

Hmm, that's odd. Assuming you used mouse move mode (default move mode), the controls should be pretty much the same as using a mouse. The tutorial is pretty brief about it (all it says is to move the mouse to move) because that's really all there is to it (there's no way to shoot or turn on focus mode, if that's what you were looking for).
Were you confused about the obstacle patterns? I tried my best at designing the levels to introduce the obstacles one by one, but I also documented all the obstacle behaviors in the game's description in case anyone wanted to reference them. Take a look at them if you haven't already - maybe it'll help?
