Thank you for playing, glad you liked it :) We had plans to add some level obstacles to kite enemies around and bullet reflecting walls to create some puzzles but we couldn't test it in time. Good idea, something like a 'portal switch' could also be quite interesting! Thank you!
Really cool Idea and well polished! Would love to see more levels with maybe a few new mechanics like a simpler version of 'lovers in a dangerous spacetime' with you losing control of the engine. Good job! would love to see the full version.
