Version 1.1. I will implement more sound effects.

Version 1.2. I will implement a helping assistant (a robot who is supposed to help you go through the level).

Version 1.3. I will implement a super jump ability.

Version 1.4.  I will implement working enemies.

Version 1.5. I will implement even more sound effects and fix some of the current bugs.

If you want, you can say what i need to implement in the future updates, and i will do exactly that if it's a good idea and other people have the same opinion like you. Thank you for understanding!
