Post-mortem balancing

Hey ents !

I've tried to fix the buttons (yet again). Do post bug reports in case it's still wonky !

Other than that... The most clear "bug" we had reported was the fact that the difficulty scales horribly bad, by the time players reach wave 4 they're destroying enemies before they even make it on screen. To compensate for that, I've tried to give the enemies more HP according to the wave we are currently in, capped at 3 x the normal hp rate. I hope this will be sufficient in balancing the game !

Either way, I hope you enjoy !

Cheers,
