Nice game, I can see its shaping up from its sprint one version. I like the change of mechanics and I think the dash works very well. For the last sprint I would recommend adding checkpoints as levels get longer, I would also recommend you fix the repeating background. As Tcilered said level 3 and 2 are a lie, so implementing them would be good in sprint 3. I personally would love to see a credits screen and a revamp of the menus to show the games charm.
