I just didn't enjoy the mechanics as they were.
The game kinda felt a bit random to me. I managed 124 seconds on insane with power-ups, 48s without. I kinda just felt that the basic action - with blocks flying faster than our mind can really comprehend and our avatar moving through blocks that are meant to push it - kinda often feels like 'push and hope. Sure, I understand that the optimum strategy would be to move towards sparser areas, move around obstacles... but having stuff move through us kinda makes a mockery of that and I guess I just felt the gameplay was a bit shallow.
The graphics were cool though and I liked the way you had various designs and colours. The general aesthetic and music was cool too.
