This was fun, I've never played a game quite like it before. It's very cool that the player can choose their playthrough goal, it reminds me of undertale or knights of the old republic in that sense, and it's done effortlessly here (in the good sense of the word, meaning it looked deceptively easy when complete) as a core game mechanic.
I liked the nostalgic presentation, we don't usually see games with players at this small of a scale on the screen that often these days but in this game it makes perfect sense since we need to see the environment.
I also liked the level design in the top right corner. I feel like in games from around the Atari era developers were more willing to put less organic looking shapes in their levels, and it felt nostalgic to uncover that area.
