Thanks for your feedback!
1. I already increased the speed of the movements of player and enemies, however I don't know which will be the best speed for them
2. I will add something so you know the platform range of movement
3. I tried to add a small jump with bad results, I will try again
4. I agree, I will try to fix it
5. Already fixed in the next beta
I know it's just your opinion, but you made me view the project from a different perspective
Let me know if I can return the help!
