Heey, thx for trying our game. It's true the booster can be frustrating because you can hit it accidently. Happy for us you can sell the booster We also know alt+enter isn't working properly but alt+enter isn't an offical key. If you change it in the options it just works fine

We are planning a release with more stages and fix some and look at the booster. Maybe it's better to use another key or something for that.

Grtz
