You've been unlucky enough to find the most difficult bugs I've been trying to face in this game
- In level 4, there is no such thing as a timeout, you should have been able to move downwards without any obstacle... that's a bug I haven't been able to reproduce myself, but you are the 2nd player who faced this one
- Level 5 is just too difficult, I need to balance it
- In level 6, I think it destroyed because somehow the turrets shot the rock and it got destroyed... I'm not sure how it happened without you being there tho, I'd investigate that for sure
Your suggestion about a tool or option to destroy all the matter is actually a very good idea! sometimes the game requires to be too aware of too many things and I agree this could help balancing gameplay
About music: I still need to figure out this one, I've been thinking about just adding background noise and in some meaningful moments, to add music
