I can't believe this was your first jam, and you don't have more comments yet! You did a really great job on this! I finished the game. I really had fun playing. The controls were good, and I look forward to seeing more from you. The platforming was fun and challenging and being able to attack the bad guys was great as well. The only suggestion I would have would be to make the attack range maybe a little farther that way I don't have to wait for the enemies to get right next to me.
Oh and something else I enjoyed was the story! I think it was really cool how you incorporated the story into the game by putting it at the top of the levels. That was a really clever way to include it. It's great to see you using Godot as well
