A preeetty good start~ ^^_ esspecially for some1ne doing all of this on their own :p I can certainly tell that xou have a penchant for storytelling UwU xou've got a lot of great ideas, so I would really like to see them brought to life in the way that they deserve :)
The 1irst thing I advise xou to imporove upon is the inner dialogue box. It's a bit difficult to understand when Greebent is speaking to himself and when he's speaking outloud :/ perhaps xou could change the shape of the name box? Or maybe even remove the name box all together? :3
2econdly, I'd ask that xou postedit everything that xou've written so far. While I was able to get the overall vibe xou're going for, some scenes could benefit from being fleshed out a bit more. I do understand that English not being xour primary language could contribute to things getting lost in translation, but a bit of fine tuning never hurts :) I think xou'll find that going over everything xou've written will not just help with describing xour story better, but it will certainly help xou grow as a writer UwU
I really do think that xou have something good going here :D the story is fun, the lore is extremely creative, and I'm really interested to know the characters on a more personal level~ ;) I think xou've done a fine ass job so far, so keep at it! n__n/
