First of all, thank you very much for playing my game. I released it very prematurely, even though I was aware of these problems. I sent it to some friends of mine and they also mentioned the movement issue. I also think I didn't program the jump properly. I'm going to watch more video tutorials on platform games. Your analysis was very complete and honest. I'm going to give it a few weeks to think about what I can create again. I still have to fix bugs related to collision shapes and viewports. I tried to open it on my cell phone and realized that I have something very promising. I feel bad for not programming well (I have a bachelor's degree in Computer Science and experience in software development). I feel like I ended up programming stupidly. I didn't even stop to do a GDD. I just wanted to make something well-rounded and put it out there for everyone to play. Thank you very much for playing and giving your opinion.
I mean, you already have at least two games uploaded so you're doing way better than most people! Game design is hard, there's a reason so few people finish them.
You shouldn't feel bad about anything with this game. It was the next step for your journey and it sounds like you already have ideas to make your next project better!
Thanks for sharing!
