With the feedback I got after the jam, I sat down a little bit and added some features as well as changed a few things.

Heres a quick list:

Main Menu:

     - You can see more information about the game such as controls, the scope, etc.

     - There now is a level selection with all levels unlocked from the start (do play the story mode first though)

     - You can quit the game now!

Player:

     - Added a little bit of friction. Horizontal movement is the same, but jumping and landing are more responsive now

     - Increased the amount of ability-uses in some levels

     - Wider ground-collider so you can jump off of more places. Sadly, I can't get a "perfect" one because for some reason, if it's as wide as it should be, you can jump when standing directly at a wall even when the colliders don't touch, which is obviously not what's supposed to happen

Levels:

     - Some levels are easier now (especially level 10 where some people got stuck)

     - Changed layout of level 12 partially so it's easier as well as not being able to cheat it anymore

Miscellaneous:

     - Press escape to go to the main menu or quit when you're ingame

     - You can now see what level you're in

     - Fixed some typos

     - Projectile-catching is a little more consistent now

     - The Quit-Button in the end screen isn't blocked anymore and you can actually press it!

     - Death counter: You can see how many times you failed after completing the story

I feel like I forgot something, but that's the most important stuff.

I dont't think I will continue working on this as I really just wanted to add the things I had initially planned on adding as well as react to the feedback I received, so I did just that. I hope you enjoy!
