Hi there,
I've tried the game, here's my impressions!
I had serious problems with controls. Xbox controller is not mapped correctly (the movement was working fine, but not the other keys), so I've played it using the keyboard.
To be honest, I've found the controls pretty bad, initially. Then, after a bit of practice, I learned how to use them. The main problem was that "W" is for jump, and space is the teleport.
After a while, I discovered that the left-click could be used for teleport as well.
I know it's written in the game page, but many player (like me) downloads the game from this page directly.
As a suggestion, I would map "space" as an alias for "up". Furthermore, I would add some kind of in-game tutorial :P
I've appreciated the good difficulty curve and the level design in general. The jumps are well calibrated, even if I died a few times before discovering the double-jump. LOL. TUTORIAL!
Maybe for the contest version, I would add a few more checkpoints, since sometimes it feels a bit frustrating because some colliders were not 100% polished.
Summarizing, I think that this game has good qualities, and could be MUCH better with an initial tutorial explaining the controls AND the double jump as well.
The gameplay choices are interesting. The killer feature is, of course, the teleport, that gives the player a LOT of air control. For instance, it can be used to pass through objects AND to stop the time while deciding what to do.
This is a great approach, because it turns a frustrating game mechanics, like the "jump of faith", into an original and challenging gameplay sequence.
Definitely, I think this is a good entry for this contest. I'd sure try an extended version.
Good luck!
