Thank you for playing, and for the detailled feedback really appreciate it :)
I'll do my best to improve models & animations so they feel more alive. As of the gameplay I'm planning on doing more levels, and making them more based on the actual puzzle part rather than runner.
The runner was to force the player to think quickly and use the rewind mechanics with the right timings since there's no choice on forward movement. The level story is to run quickly to the portal before getting swallowed by the sandstorm (not really clear in the game but will improve that!)
