Loved the original cursed treasure games. This one looks good too, however I can barely play it due to incredible lag on my (1yr old) laptop. Even with the lowest quality settings, it's basically unplayable, sadly.
Really love this game. Great mix of towers, add-ons, upgrades, and just the right amount of active abilities. Love how some add-on combos can really complement each other. Great level design, and difficulties are just right. And just when I thought it couldn't get better, the challenge mode was a really fun way to provide an extra kick after you've mastered your stratagies and force use of different ones.
I made a little autohotkey (google it) script to automate fishing in case anyone's interested. You may need to tweak the coordinates in the PixelSearch, but these worked for me in Chrome with the browser scrolled so that the game's upper left corner is near the window's upper left corner. (Press ctrl-1 to start, once you install autohotkey and run this script.)
