I would love to for there to be slightly larger collision on the small disappearing platforms, or maybe to stay physical for slightly longer. I'm a novice to platformers and keyboard controls so take my suggestion with a grain of salt, but it's kind of frustrating to just keep trying to redo a jump for 10 minutes. I've also had enemies spawn on me immediately after I respawn on some checkpoints, but you're probably aware of that. Over-all, I am really impressed with the game and want to see more of the world. I also enjoy how you bring out a relationship in the character dialogue, so the pilot is not a dry, flat-out quest giver. It really feels like a professional quality game just a few updates away from a really polished experience.
Good job on the level design as well :)
