Fun time-waster, no strategy

I like the graphics (the little fish in the lake at the Stormfront shop was a nice touch), but I wonder if some of the details could be tweaked to allow more strategizing. Since the range weapons are so much more powerful than the blade weapons I found myself never using the blades. Using blades regenerates energy faster, but not enough to warrant using them. Perhaps the blades could have a quicker regeneration, or they could be cheaper so that you are encouraged to upgrade them first until you get more money.

Excellent game, possible bug

So many games are lame immitations of existing games, but this has unique puzzles I've never seen anywhere else.
I wonder if there may be a bug in the log one (#8?) all logs are down and highlighted in green except the shortest one, but the system doesn't seem to want to accept it. I've thought other things were bugs, only to realize I just didn't get it - but in this case it does look like one.
But excellent work either way

Rare to find a good educational game

Most educational games are too boring to stick with, but this held my attention for about 4 levels. To keep it fun, I would add a few more abilities, such as a laser gun, needed to blow up obstacles. I can see kids actually learning the concept of subroutines by playing this.
