I played both web and win versions.
The procedural generation seems to be needing more work.
Its kind of laggy and blank spots sometimes appear.
What I would like in the game is the possibility to keep the attack button pressed.
Spamming click for every attack is a bit frustrating.
I enjoyed the world naming idea from sandbox. Reminds me of Terraria. I think you could go that route and get a really nice game.
I enjoyed more the web version. But I am sure the sandbox version will get there eventually.
Well done!
