List of bugs I found:
1. Where the laser comes from if you hit it you won't bounce (someone probably forgot to change the collision)
2. When you press tab while your playing then pick an option it will make your character move depending on what you click (When you press tab it also freezes everything except you)
3. If you look closely at lvl 2 the texture for the blocks that move is a bit off and there's a wall like that on lvl 8 too (Why didn't the play testers find this?)
4. On lvl 5 if you shoot yourself towards the dynamite in the middle with the perfect angle then you can end up damaging the brick in the bottom left (I think that's because when you die your movements still exist but you just can't see yourself)
5. If you stay still the red circles will shoot in the same direction (probably because they shoot towards you)
6. On lvl 6 you can glitch through the wall (Hit the switch in the middle then go to the win area once your there with the perfect speed launch at the middle switch with enough power to be exactly in between 2 walls)
7. When the red circles touch the laser the laser stops at the red circle but when a red square touches the laser the laser doesn't change at all (there is a way to lure him it)
8. If a red squares touches the thing that shoots red circles it will go through it and you will only be able to see it's face (expect the unexpected!)
9. If you go close to the laser and wait for the square to kill you part of the laser will disappear (Maybe they used the similar code for the player and the red circle?)
10. The red squares destroy the bricks in 1 shot instead of damaging it (copy some of the players code that makes it able to damage the bricks)
