Summitatem Glaciem by The Dreamweaver
My very first Ludum Dare (sure you can tell). The title is the best possible Latin translation of "Tip of the iceberg". You are a research scientist who stumbled upon this iceberg that stretches several miles beneath the surface of the water. You must dig deeper into the iceberg and get to the end, collecting research along the way. Uses 'wasd' controls to move. Use "s" to go down into the cracked ice. Thin ice breaks after a few second after standing on it. Hit "s" while standing on the cracked blocks to advanced to next level. Avoid enemies, but you can also attack by clicking left mouse. You must collect the research books from each level to beat the game, other wise its gameover. Hearts increase health. You also have to watch your energy, as the lower you energy the slower you go. By the end you should have at least 9 research books. Extract the folder and plae the .exe.
FYI this shouldn't be tagged as "web", that's for games that are playable in the browser.
