Okay, one more cube running game but yeah, well-integrated and well presented with a slightly modified concept. However, I would suggest you increase the difficulty slowly rather than rising it up from the lv2 or 3 itself. This will help the users to have more engagement and retention. The last jitter effect that you have implemented doesn't look that good so consider changing it or else remove it completely.
Looking forward to seeing more such awesome projects, all the best for your future works.
