Complete revamp of the game's programmer art into something more easy on the eyes.
Because I didn't want to go through hassle of animating new sprites, for objects and actors (aside from Player) I used open source art.
Terrain tiles, concrete platform, player character sprites, icicle and bullet sprites are done from scratch by me.
The new Tentacle Monster (medusa) and Flamer walking and standing sprites are shared under Creative Commons BY-SA 3.0 license.
Everything else is shared under license CC-BY 3.0. For edits (entities) please share the original creator, not me. But for my original graphics - terrain, icicle, blaster bullet - please attribute me, Shino1.
