Some games I'm proud of making (ordered descending by time of release):
The Tower Defense where you cooperate with the attackers.
You are the most famous person on Earth. Your fans are crazy. Shoo them away! (with airstrikes). 3D arcade game.
You are god, and you are broke. Make money by telling fortunes and then changing the future to match. You make the level. Using equations. And the computer plays it! I made all the visuals myself too :)
2D procedurally generated escape-the-dungeon. The Joker runs from the King's castle after a joke went too far.
2D arcade game with procedurally generated levels. The sky is falling, literally. Dig deeper and deeper to escape it.
Short isometric AND first-person game with a novel camera mechanic. You were hired to take "authentic", i.e. beautiful photos of a city. The city is ugly though. What to do?
Top-down 3D shooter. Try to use as few robots as possible to explore the mystery of the deepest sea abyss.
