Blue Vortex current pb is 2:32, don't think i can go further than that
before that, failed a lot at around 20 seconds to 40 seconds
i think it would be nice if there were some options and more modes to play with. at first, the whole "move the camera to avoid obstacles" thing was a little hard to grasp, and i wished that there was a mode where, instead of using the camera to determine if you hit something, it used the CURSOR instead. also, after prolonged play, the "vortex" gets a little hard on the eyes, so it would be nice if there were options to remove horizontal or vertical lines from the grid (although there shouldn't be options to outright remove all lines altogether). the game over noise is also a little too loud, that could've been reduced to be less grating. obstacles that overlay other obstacles should have the ones in the back be darker or maybe a different color/hue, it can be a little trippy with the moving circles with them being back-to-back-to-back
tl;dr overall pretty nice but some things could be a little friendlier
