no problem! good thing serenitrove saves without needing to export it!
i have an idea for maybe a very very very very very very very very very very rare relic. where every 10 digs it doesn't take durability, stamima or torch life and it digs sideways to the edge of the map, then it will triple all your healing during that time, triple all your profit. maybe it could be a way of prestiging too with the relics. once you collect them all you could put them in the sacrifice well and then you prestige with like double luck (if you add a luck system.)
this is just an idea and it could use some tweaking because i assume that this is would be painful to code in but it still would be a really cool relic and prestige method.
To be honest, I originally made this game just for fun, so I built it using plain HTML and JavaScript, no game engine involved. At some point I thought, why not upload it to itch.io just for fun, and to my surprise, it started getting a fair bit of attention.
Looking back, I kind of regret not using a proper game engine from the start, since the current setup has a lot of limitations and performance issues. So yeah, I wouldn't really recommend building a full game with just HTML and JavaScript. It's meant to build websites and web apps.
If you’re interested in game dev, I'd suggest starting with something like Unity or Godot. Both are great beginner-friendly options, and I'd say they're around a 3/10 in terms of difficulty for making a simple game.
