Hello, I am puzzlefrog, but you can call me Alex if you want. I have some feedback if you want it. If not feel free to ignore or delete this. Anyway here I go. As someone who had trouble with the conversion to HTML5 myself, I know where you are coming from on that front. If you plan to continue developing this game after the jam, I hope you will find this advice helpful.
First, let's talk movement. The movement speed took me a bit of getting used to. Your character moved a lot faster than I expected him to be able to go. He is quite nimble. The movement feels rather abrupt. One thing that can help with that is making his acceleration from 0 to top speed more gradual.
Next, let's talk audio. There isn't really anything to be spoken of there. Strictly speaking, music and sound effects are not a necessity, but they are a nice thing to have and they make a game more enjoyable in my opinion. If you have the ability to add either of those things later that would help the game's feel or vibe or whatever you want to call it.
Then there is the premise. I love the premise. It is simple and easy to understand. I could see a great game developing out of that if you keep working at it. Some notes though on how the game play is built around it. Collecting the ingredients was relatively easy, but I wasn't able to figure out how to craft spells or deal any damage in combat.. Now I do acknowledge that could just be a skill issue on my part, but I thought was still worth bringing up.
I think that's everything. Accounting for the time constraints you had to deal with and the troubles that you had converting your game, I can see why the game didn't do as well as you were hoping. For future game jams. Try not to focus on what it is you couldn't do. Don't say in your submission, "I couldn't do this or I couldn't do that". Say,, "I did this or I did that". Focus on what you did right. You got your character to be able to walk, jump, and talk. Sure it could use some polish, but you don't need to bring that part up. Also don't undersell yourself. Be nice to yourself. This was a learning experience. If you learned something from this, even if you don't win, then you were still successful in at least one respect.
I have no doubt that if you do more game jams and apply what you learned here, you will do so much better. I believe in you. Good submission.
