Like the concept and art style of your game. And it ran well in the browser, good stuff!
I managed to get a time of 151.04 thanks to a little speed glitch- if you crouch and sprint into any corner, the default walk speed increases by a lot for the remainder of the run.
I've also found you can softlock yourself by throwing batteries out of the map. To recreate this bug you could try throwing them into a corner while moving. This can be accidental if you're making your way onto the charging pad and release the battery at just the right moment.
Really fun game though, enjoyed playing it :)
