A downloadable Imp Game for Windows

Can be played in any language. どの言語でもプレイできます。

Browser version should come later: for some reason, the game doesn't load online as of now. I'm assuming it's a font issue.

Plays with keyboard, and mouse is strongly recommended for camera control. May be compatible with controllers as well, but camera control will be more limited.

WASD or Movement keys for moving. Z to confirm. Hold X to bring up menu during gameplay. (Note: The game still runs while it's open!)

Q/E are used to rotate the camera on keyboard. It may be possible to beat the game with only the keyboard that way, if you really can't use a mouse at the same time.

Hold Shift to activate your detection mode. You'll move slower, but after 3 seconds nearby books will radiate to make them easier to find. Books that are REALLY far away still won't be detected like this though.

Each stage lasts 2 minutes at most and there is only 4. Find at least 6 books out of 9 to pass (2 in the tutorial). 

Don't sweat it if you fail to beat a level: you can restart from it.

This is really fancy for a game jam game! Got 28/30 my first try (with 1 death in stage 2). I was curious if there were different endings based on performance so I tried a 2nd playthrough but quit after a book escaped in stage 2.

Thanks for playing! There is a change in the ending if you get a perfect 30/30 with no retries, but it's quite minor.
