The port to UE4 (4.27.2) is on the right track. It doesn't have the level art yet (I don't think it will in a long time) but the mechanics are more polished, and the feedback when hitting enemies is a million times better (as you can see from the screenshots!).

I'm currently using borrowed art such as models, particles and sounds, there's nothing mine except the logo, game design, level design and code (for now, all Blueprints). The music will be made by me, when the time comes!

 I'm trying to make a proof of concept, so I can use it as portfolio and to also make some artists friends of mine jump to my ship.
