Honestly, really well put! It works fine, I didn’t experienced any bugs!
My only concerns are about the controls:
- The jump on the space bar for both the jump and the boost results in me flying in the air uncontrollably (it feels like rocket league) and not boosting at all.
- The fact that the keyboard layout is not taken into account (it is really easy with godot, check it out).
For “not so expansive” gameplay/design ideas:
- Maybe bonuses and maluses would be interesting (like bigger wrecking ball, high rotation speed, etc.)
- Maybe you should put more levels, smaller but with increasing features (ennemies, bonuses, maluses, etc.)
Anyway, good job!
