Great sound track and art, good dialogue and story.
Nano Driller is a small, fun game with unique controls. You fly a ship around the level, unlocking new areas by solving some simple puzzles and collecting keys, and culminating in a boss fight against some antagonistic buzzsaws. An unhurried first playthrough takes less than an hour, and practiced speedrunners can complete the game in under 3 minutes. The controls are simple to understand but tricky to master, with what I found to be an acceptable learning curve. There's some nice incentives to replay, with two different manners of piloting the ship, an unlockable "gravity ship," and the ability to enable "chasers" for an extra challenge once you've demonstrated your mastery of the controls with a sub-7 minute playthrough. Minimalist graphics and a couple of catchy electronic beats that don't distract from the gameplay. If you like Nano Driller, the dev's jam game "Cell Driller" which is basically a one-button prototype of Nano Driller, is available for free.
