Level redesign

To prevent mindless meandering and create a more concise experience, I have redesigned the first level of this demo (Level 3 in the final game) to be more compact and logical, so players shouldn't get lost anymore.

Also changed:

- Upscaled resolution

- Fixed annoying bug of accidentally leaving rooms due to poorly placed teleporters

- Changed font for HUD

Thanks a lot to Shaun Spalding for featuring my game on his stream and giving me good pointers, adjustments to controls and collisions are on the way as well
