I've finally managed to finish my little "Gemcraft Chapter 0" Encyclopedia.
Here is what will hopefully help all the Gemcraft 0 players: Gemcraft Zero Repository
Explanation of the fields in the picture: 1 - shows the naumber of monster waves in normal mode in the current level; 2 - shows available gems; 3 - shows if there's a lost amulet available in one of the modes of the current level; 4 - lists the modes with 3x experience bonus; 5 - shows gems you get at the start of the current level (gem level, color components, number of gems of this kind); 6 - displays the ID of the level and additional information if it's somehow special (hidden, arcane, etc.); 7 - shows how the level looks like, so you can prepare and plan some strategy;
How can this stuff help you? Well, if yo havent's seen all the levels yet you can get a sneak peak and get ready for what's about to happen to you. If you already have all the levels available you'll probably want to score better, especially when you find out in the forums here that you can make millions of exp in one level. Choosing a nice level to play is pretty time consuming within the game - you probably don't remember how all the levels look like, what gems you get at the beginning of the battle... GZR is just for you - you can browse through all the levels and choose the one you want to play next.
Unzip the file, enter the GZR folder and run Game.exe. Controls are only Left/Right to browse through the maps (and Space to get some info). This is also the place where I should thank to iri for posting all the lost amulets.
Oh yeah, although I did my best so this would be free of bugs it is possible there are some left. So if you spot some bug, maybe some information wrong, please post it here or through the comments on my profile - I'll fix the program and update it.
Happy Gemcrafting everyone!
p.s. On a sidenote - this application is strictly a fan work. Gemcraft hasn't been hacked to do this. Just printscreens and some own graphics and coding
