Ohh!! That's pretty good! Usually I can't get much past 20 myself (initially I could only get to 12-15). At first I was concerned the game was too hard, but then when I realized a big trick is to make a loop between the 3 health upgrades I was able to hit my 42 high score before I got ambushed.
Two of the health power ups you can see the sparkles but not the item itself so it's a little hidden (one is behind a tree, the other behind a building), but still can be spotted when you aren't panic running from 5 enemy tanks at once lol
Glad you enjoyed! Tanks for playing! (yes, I had to lol)
