Very nice and interesting game! The difficulty was a bit high I would say, but mostly I think it is because jump was using space instead of up button like we are all used to.
Thank you for playing and leaving feedback!
I always like using Space, but I'll upload an updated version that allows W/Up as an alternative for jump.
Now that the rating period is over, I've uploaded a new version, containing 24 bug fixes and new features in response to community feedback.
You can now jump with the W or Up Arrow keys. :)
Feel free to check it out, and thank you again for sharing your feedback!
