Thanks for the game! I almost got 24 in, but didn't quite manage it.
A couple of points of feedback:
- The tutorial needs ALOT of work. It's not at all clear how to play the game from the tutorial, and it doesn't at all mention the buttons to use.
- I found it got very laggy in browser after putting in one or two sets of energy.
- I'm not sure you need the shooting element; I found it's easier just to avoid them and conserve the battery.
- I don't think you need the cog element at all; it's just annoying as a player to have to find the cog first, which could spawn anywhere; the point of the game is to pump the machine with energy, and having to use up time (and more importantly battery!) just getting the machine to even work is just feel-bad.
- If you put energy into the machine and have the energy pick-up fired up, but then you pass through the machine again, it converts the energy you've picked up, but it doesn't create an extra energy refill pick-up, which is REALLY annoying as a player; you should add some code to the machine that checks if there's already an energy refill pick-up sitting there and, if it is, not allowing the conversion of energy bolts through the machine.
Thanks for making the game, and I hope you enjoyed the process!
