A great little prototype and nice selection of easy puzzle levels. It would be nice to take the concept further, increasing the difficulty level (I was able to complete all levels on the first attempt apart from the very first level, as I had to work out the objective). I like how self-explanatory the mechanics were. I think that the game is built out of enough familiar elements that I was able to deduce what to do in a way that meant no tedious tutorial was needed: the tutorial was almost built into how the first puzzle was designed.
This could feel so much more satisfying with a little creative sound design. Musical notes ascending through a scale each time you take a correct step, a nice success jingle upon reaching the end etc. I'm not sure why, but your sound effect for the tiles is only coming out of the left speaker.
An interesting character design to replace the capsule would also be great.
OHHH, and I loved the camera follow. Very cool.
Definitely worth exploring and developing this concept further. Thanks for sharing!
