Polarium is an abstract puzzler with a simple premise. You must guide a glass cube along a set route of black and white tiles, whilst polarising the background to protect the cube from being destroyed. This intense and rapid gameplay mechanic, revels in the same class as classic SHMUP Ikaruga, but has the pacing of slower, cerebral games such as Portal.

Elona is a free roguelike fantasy RPG. You roam from town to town, solving some set quests, and as many random quests as you'd like. A range of fighter or wizard classes are available, as well as a few odder classes: farmer, performer, etc. You can hoard gear in your own comfy cave, and expect merchants and trainers to drop by once in a while. Choose a loyal pet to join you. I typically opt for the violent little girl.

The bunny killing platformer Mayhem Triple is finally out, after about 10 years in development. I remember following this one back in the day, then I stopped following it about 6 years ago when it didn't look like it was going anywhere anytime soon. :)

Just an FYI: I'm not dead, but my PC crashed and thus I have no idea how far I got... Perhaps I'll continue when I can figure that out

If you do decide to continue, perhaps it might be easier to start from the end, then backtrack. Thanks for the work you've already done, btw!

Lumber Island - Indie/Horror/Adventure/Quest. You awake to find yourself in a life-boat ashore an island, and the last thing you can recollect is having fun at a great yacht party. A bit of history: Back in 1970s, this island was known as the "Lumber Island". It abounded in rare wood species of the highest quality, which were sought for by the craftsmen from all over the world — many of them took trips to the island in person, to pick the best material. The island thrived on private manufactures and tourism... ...until deposits of oil were found under it. This finding doomed the island: its inhabitants were made to leave their home land, the wood was chopped down to the ground. And after the oil had been pumped out to the last drop, the island was left abandoned and totally exhausted. This is the official story. The real truth lying behind it is for you to discover...
