You deserve a lot of credit for being able to create your first game without any tutorials! I don't think I could've done better before learning how to use the software myself (and I’m definitely not claiming to be a pro, far from it!). But if you’re able to make something like this without any prior knowledge, then you have a lot of potential. Keep it up!
I'm not a native English speaker, so the narrative aspect of the game was a bit challenging for me — I find that too much text in another language can hurt the atmosphere a bit, because your brain has to work harder to follow along.
I also noticed at least one missing asset at the top of the first screen.
The character moves a little slowly, It would feel better if the character walked a little faster.
In any case, great job and congratulations!
