various improvements

- console temporarily enabled DO NOT RELEASE
- game is bigger (a bit more difficult) and in 19x6 resolution now
- fullscreen explicitly false to prevent fullscreen happening when
setting resolution to monitor size
- time limit added, with game over screen (needs work)
- code adjusted to work with any resolution (assuming in 20 px
intervals)
