Both of those are fixed as of today, give it another go.
The perfect-wave bonus was quietly handing out a second bonus on top - 8 bonuses instead of 4 across a level - so whoever took no damage just ran away with it. That's gone, it's points now. And the energy bar moved down: five dots right under the orb you're about to drop, red when you're empty. You were looking at the top of the screen while your eyes were at the bottom, that was on us.
One you didn't see but probably felt: a leaked enemy used to steal energy from you. Between that and the kill bonus you never got, a door with no turret could lock you at zero and the game would refuse every single drop. Also gone.
Obstacles on the board - rocks already turn up from level 8. Enemies messing with your grid is a real idea, I'm keeping that one for after the jam. Thanks, yours was the most useful comment we got.
