Post-jam updates

Now that Jame Gam #53 is over, I've updated the game with feedback received from other contributors.

• The sliding chips and the bugs now animate their movement, rather than having staggered movement. 
• The Burst Chip effect graphics are now 8-bitish pixelated, like everything else
• Added a level indicator in the top left so players can keep track of how far they've gotten

Future updates will include:

• More thematic graphics for the player
• Better audio (now that it doesn't have to be guitar-based)
• Animated Burst Chip effect graphics
• Achievements for certain tasks
• Saving progress
• Different types of chips
• Different types of bugs
