Chalk is a game where you draw lines using the mouse to connect on-screen objects. But it feels like a fast-paced shooter, complete with several creatively-conceived dsddsddboss battles. It is quite well done and I recommend you try it out if you like games that are different.
There are some bugs in the game, and the nigh-mandatory fullscreen mode doesn’t work perfectly. But the game is well worth suffering these issues.
I would love to see a version of this game published on the DS or Wii.
