0.6 Release

Changes in this release:

• Added temporary workaround for mobile inputs, as the game struggles to automatically detect phones. Will probably add downloadable executables for Android and iPhone when the game's closer to complete.
• Added a quick in-game tutorial on start.
• Fixed a camera shake issue with the first boss.
• Fixed a bug with the second boss that caused the game to occasionally crash.
• Fixed a sound issue with the second boss.
• Fixed a spawn issue with the third boss's kitten minions. 

Plans for future release:

• Add sounds and music.
• Add a couple extra bosses and randomise boss encounters.
• Add more 'cannon fodder' cats to make the in-between waves more challenging and varied.
• Add optional targets to increase score.
• Add a power meter and a special move.
• Add rogue-like upgrades and temporary power-ups.
