Should also implement proper level borders, or e.g. wrap the player around the border / follow the player with the camera, so it's not possible to get out of the camera's view. Keep adding content!
After nailing the controls (it's easy to get damaged if attacking from too close), I was expecting new levels or some more content (enemy variety / pickups / difficult places to get to etc.). There is no double jump, so I got stuck in a ditch at one point. :(
Thank you all for your comments, suggestions! I too get the feeling, that there should be a way to make the controls easier. For instance, a similar game, https://store.steampowered.com/app/846030/DV_Rings_of_Saturn/ provides autopilot from the get go, albeit, that game is a mining sim with less action, and even steeper learning curve. Possibly, there will be an autopilot / flight assistant component before I implement any ship customization, which can be turned off if you are looking for more challenging gameplay, or e.g. want to glide onwards without breaking.
