For the first game it's pretty solid, it works with a few bugs, but I would definitely add descriptions to items, because I can buy something, but I still have no idea what they do or if they do anything.
The speed would also be greater for me and that can certainly be improved by greater diversity and more enemies that do something different.
It would be also better if more animations and textures would be added,
exaple, sometimes I didn't knew what happened after I broke a door or if at least something happened.
I also miss Txt from gold, because I don't know when I get it
That's basically all for so far.
I don't know how many people made that and for how long, but now I give it a 5\10.
It's not bad for the beginning, but otherwise nothing exciting.
