The atmosphere was really cute and beautiful — I really liked the art style you used and the animations, especially the way the enemies walk. You did a great job with the music and sound effects too, even if it was your first time producing them.
Well, since this was your first game in this language, I’d like to suggest a few ideas that could improve the gameplay based on what you’ve already created, as they would only require some code adaptation to implement new mechanics or forms of interaction.
The first idea to make the game more challenging is: enemies could walk to random points on the map. This would greatly increase the sense of danger and difficulty, as we might end up surrounded by crowds of opponents.
Another interesting point is a way to temporarily increase the character’s speed — maybe by using one of the resources we collect as fuel? I believe this would be implementable since you’re already able to control the speed variable, so I assume you could modify it temporarily too.
The controls were responsive, and for a first project of this kind, I’d say you did a great job. Once again, congratulations on that and good luck in the jam!
