It's been several months since I last played. I remember I wasn't very good at it, but let's see how I do this time.
Going to the settings I still see that the text is cut off for Control Preference. It started on "WASD TY", with the Y being more than half cut off. "OFF: also overlaps the text on the other 2 options. I am playing on Linux, so if you are using Windows only fonts, and not bundling them with the game, then that is likely the issue. I don't know Scratch, so don't know if it has an option to bundle your chosen font with the game.
I went into the Tutorial to see what the other controls were, but it looks like the WASD TY controls are hard coded there, as choosing any other did not alter what is shown. I'm guessing WASD O would be followed by "P", to match T & Y being side by side.
Holding W & S together feels odd to me. I have to rotate my wrist in a way I'm not used to for gaming. You aren't using Space, "Q", or "E", and I think any of these would work better than the WS combo.
On the Tutorial "Try It Out" screen I was able to go off the screen at the top, though bounced off the other 3 edges.
Why does the equip screen require using numbers, instead of clickable buttons? It feels odd to be switching from a mostly mouse based UI, to having to type letters and numbers for equipping.
Having a Tutorial is helpful, but ideally the game controls should be clear while playing. If you don't read the tutorial, you may get to the combat start screen and be confused as to what to do. I would add text, or an icon, informing the player to press enter to continue. Adding Space as an alternative would also be nice, as that feels more natural, to me, with WASD or arrow key controls.
It would be nice if there was more info on the things you can buy. When looking at the Jouster and Kujang, both say "Average damage". Does either have an advantage over the other? Maybe the Jouster would be longer? The image makes it look that way, so that is what I went with.
I took a look at the 1v1 screen. When scrolling to look at the weapons it also scrolled my browser window. It may not be an issue in fullscreen, but I like to keep it in a non-fullscreened window so I can type notes while I play.
I did a bit better than I remember doing last time. I'm not sure that my skill has improved. I feel like the enemies are more balanced so they don't jump in difficulty so fast, especially when I lose. I was able to win a few fights, but never enough to get more than basic equipment, and no abilities. I got a 10 HP helm, then a 30 HP one, and the Jouster. I mostly got some luck blows to win, and never thought I was all that good at the controls. I felt the need to spend on whatever I could afford as I know my skill was not high and I could lose money by losing the next fight, so spend it when I had it on whatever was affordable. I know you have the 1v1 mode, but I didn't want to go through every item trying them out. I'm not really a fan of the rag-doll spinning controls, so am not motivated to try out all the combos. This is amplified by the fact that when playing through I rarely get enough money to buy more than basic gear. If I liked the style more, then I could spend the time to get better and get further. Everyone has their own preferences, and for this style of game the combat seems fine, it is just not my personal preference.
The biggest thing I think the game needs is better UI. The UI is all over. A more consistent UI would help the feel and flow of the game. Since your combat controls are purely keyboard based, I would make the entire UI work with the keyboard. Every screen should grab focus on a control and allow using the arrow keys and tab to navigate between them, using Space or Enter to select. Even with the mouse, some UI elements were annoying. The biggest was browsing the items to purchase. Thin items could be a pain to click on. For the UI it would be nice if all items had a preset rectangular area you could click on, rather than needing to match up to the shape of the item. Also, the selected item's info pops up over the middle item, which generally means I had to click off to make it go away before I could select the center item. And, the above mentioned oddity of using letters and numbers to equip things really felt out of place with everything else.
It would also be nice if you broke out the control settings. Have one option for movement controls, and another for the buttons for special attacks. This will give players more options. You could also add more options for the specials without needing to have combos with both WASD and arrows. This could also allow for adding additional control options, such as how to face an enemy.
