Here I gave building to WebGL a try and it seems to work wonders. My high-score seemed to be caching on my end so I hope that for the user's end it caches as well.

Here are some minor tweaks to the game

• Reduced the interval between power up spawns from 30 -> 25
• "Insane Player Bot" removed. (Being used as guinea pig for the 'Smarter Enemies' update)
• Pulled bullet spawning point backwards. The bullet was spawning one block further than before

This week I was shifting rooms and de-cluttering my house so I was really tired and couldn't focus on getting the next crucial update out this week but path-finding and the Cartesian axis correction is working already and I could probably get a working unit by next week.
