I really loved the concept and the character. Some things I didn't like is, the terminal is pretty cluttered and the checkpoint icon is a bit hard to get. At first I though it was a new ability or something. You could've added some text.
Except that, the whole game feels really good. The level design and the gameplay is pretty fun. Although I should say I am not a big fan of backtracking. It's a totally personal opinion but I don't like it that much. Overall it was a really solid game with a lot of fields for improvement. I would really suggest you to develop it further and make a full fledged game out of this!
(I forgot to say something last time because I played the game before voting started 😅)
