Hello again, I don't know if you're thinking about it, I have some suggestions, I'll pass them on to you. I feel the world is a little empty, it's not bad, it's a BETA and it's understandable, I would tell you to try to add more life, big enemies are good, but you could add more life, for example: add small enemies which have some small weapon or none, add rocks or some obstacle, you can also add plants or something that interacts with the player beyond the common enemies. I don't know if you've already thought about it.
I am working on a new general improvement for figures (a new slot) in which one of the things it does is change the skin, since the normal skins are colors, this would change the internal drawings of the figures, allowing me to create, for example, a rock texture, and would also have some effect on the game mechanics. My idea is to make the enemies all based on geometric figures, I don't know to what extent I can do that.
