Hi, congrats on your game! :) I really enjoyed it, especially the mechanic of making a long jump backward. The mechanic of altering planes is also very good, but I felt the lack of some more introductory levels. The first level with the mechanic is already quite difficult, and it took me quite a few minutes to complete it... But apart from that, it's a great game, congratulations.
If you have some spare time, please try out my game. It's a classic space shooter from the 80s but with a personal touch. Please leave your honest feedback.
