The character animation looks really nice, especially for sliding on the ground while shooting a laser. In general, the artwork in the game was really nice.
However, I think the movement mechanics felt a bit janky. I had to do this weird tiny wall jump to get over a ledge, which felt out of place for me since I did not use it after that. I also think the monologue cutscene at the beginning should be optional (or skippable). Some of the voice acting was hard to understand because of the accent.
But overall, an amazing effort for your first game.
p.s. if you were aiming for an emotional ending, you did a damn good job.
