I agree on the 'no leveling' issue. Honestly, I think that tool tiers (bare hands -> wooden -> stone -> iron (-> diamond) ) serve the same purpose, and they feel much more natural and intuitive than "Congratulations! You have reached level 977! You gain +3 Str and +1 IQ!"
The 'sunlight damage' instead of fire was actually kind of required, even if it is less cool. The issue was, Skeletons could sit in water and pelt you with arrows, and the water would completely negate the burn. (Zombies, too, but at least they had to leave the water to attack you!) And, of course, it's practically impossible to approach a Skele while swimming.
Oh, and yes, you can indeed find water on Floating maps - my most recent floating map had a small pool in the middle of a sand pit. Which scared the ^&%$ out of me, because sand pits can spawn without dirt beneath them. Mine one tile, or build anything connected to them, and their physics turn on again --> the entire layer collapses! Luckily, this particular pit had dirt beneath, and I constructed a nice little irrigated farm near my tower. (Before getting bored, that is.)
And, as for purchasing the game... it's not in English? To be fair, the developer is Swedish, but I distinctly remember going through an English purchase window.
I just tried creating a new account, and hit the 'buy now!' button in the top-right. I went straight to the Paypal window, which was in English. Never saw a word I didn't understand. dragnar, could you clarify your issue? What, particularly, isn't English?
