This is really polished and has solid gameplay. I liked the teleporter mechanic (though I initially was a bit confused because I thought it would teleport me to the other teleporter). The run-back mechanic was good too, though I would have preferred the level to change more and for the changes to be near the start of the level so that you aren't caught off-guard as soon as the heat wave starts. I wish there were some more levels, especially with the teleporters. Great animations and music. Nice work!
