All right, here are some ideas for improving the game, in order of how much I wanted them. (For the record, I was playing version 0.5.2 on Firefox):
The biggest thing that would have helped me is: a tooltip for every stat! For quite a while, I was confused about things like the subtle differences between Armor, Defense, and Mitigation, or how HP5 differs from regular HP.
Next, I was confused by some of the numbers I was seeing. For example:
Here you can see that my red health orb is at 155, whereas my Max HP is at 150. That seemed impossible to me--and, yet, there it was...
There were other things like this. For example, my HP5 stat was initially at 1, until I ate a carrot with an HP5 value of 1, and then my HP5 stat jumped to 3. Later, when I had eaten both a carrot and a chicken leg, by HP5 stat was also at 3--which seemed impossible to me. I became less confident in the game as a result.
Next, I was not able to find a merchant that would allow me to sell some of my items (e.g. Club 1, Armor 2, or Legs 2). What I really wanted was a "Sell" button below the "Equip Item" button when you examine the item. It was frustrating not to be able to clean up my inventory, and (occasionally) I needed the money and really didn't want to hunt through all of the previous merchants to find the exact one who would take my item. A "Sell" button would have solved all of my problems!
I felt that the duration of the movement animation could have been about 0.5 seconds, whereas it is actually about 5 seconds. If you have to cover any significant distance, you may have to spend some 30 seconds just waiting for all of the movement animations to complete! A shorter movement animation duration would have made moving much easier!
When you're interacting with the Merchants, there is text below the dialog that says "Click here to close". Because this text is not part of the dialog itself, I didn't notice it at first, and actually wound up traveling to a nearby location, and then traveling back, each time I needed to close a dialog. Later, when I realized how you're supposed to do it, I still reflexively searched for a close button, [x], in the top-right corner of the dialog. I kept expecting there to either be a close button, or to be able to click anywhere outside the dialog to close it. Neither of those things work for the merchant dialogs!
Twice, I accidentally bought something that I was intending to sell. This can happen when you enter sell mode, and then quickly switch to another vendor, which puts you in buy mode without your explicit consent. This can have consequences: I lost a fair bit of money both times I unintentionally did this, because it was very early in the game, and it consumed all of the money I had.
When I first entered "Cave 1:1," I was unlucky enough to get seven non-monster encounters in a row. There was absolutely nothing for me to do except wonder why my character kept trying to pick a fight with a rock? It seemed very strange that he considered a stalagmite to be a significant threat, since it is well out of reach and totally inanimate. I had to wait through seven non-monster encounters before I finally got a single monster to fight, and then I got another long string of non-monsters before I found the exit and got the heck out of there.
I noticed some typos in the monster descriptions:
Sporeback: "definetly" => "definitely"
Wolf: "SCRATH" => "SCRATCH"
There may be others, but I figured I would make a note of the ones I found, in case that helps :)
Anyway, thank you for the game! I think it has a lot of potential.
