The version compatible with GX4000 is now available, and the ship can now move and fire during transitions between stages.
This plays brilliantly, thank you so much! :D I have one more ask...would you be able to update the GX4000 version so it saves the hiscore on PicoGX? There's instructions here: https://github.com/Neo2003/PicoGX/blob/master/Programming.md#saving-progress-high-score-or-anything-else
