Man. You were just bombarding lots of information at once. Maybe do it gradually or incorporate it into the gameplay. Also the music seems to cut off. Not a big deal, but it certainly distracts me from the game. Maybe make it seamless or add a little pause before restarting it. 

On a positive not though, the way you incorporated the one key condition was unique

There was a LOT of unskippable text to get through at the start which was slow. Once I was finally in, I hit escape on the keyboard..I'll try again later

The introduction of everything was very well done, especially in the first part. Tho at first i thought i had to shoot the rocks instead of just hitting them with the rocket. The second part was better gameplaywise imo. It was way more engaging as you really had a lot of pressure, which wasn't exactly true for the first part. Tho the way the player has to press continue to get to the next message at the bottom was kinda annoying. The text aswell as the continue button were also outside the speechbubble on my screen which made it hard to see it at first. 

The second part kinda surprised me tho it was the part of the game that was way more fun to me, as it felt like it was a little out of context. The switching of topic and theme of the game didn't feel totally right to me. 

Overall a fun experience tho. Good game :)
