Why are the arrows mapped to a linear line? It's just trying to up the difficulty for no reason, how about hard song maps instead and having the keys lined up so I don't have to train my brain for something so non intuitive
There should also be an achievement for minimum components too or incorporate it into the current ones - I much prefer simple elegant solutions than the screen full of a million manipulators
mini guide to own: Use greens to get past first boss. When you get enough gold sell everything and buy a bottom purple in central location so it can hit at multiple spots. After 2nd boss get blue and shove a max upgraded top blue at start and whereever enemies in range of your purple. For remaining bosses build enough top greens to kill them then sell after that round. Sell purples for final 2 bosses and spam top green everywhere. Buy yellow element after 2nd last boss and spam some maxed top and bottom yellows for decent dps and slow. After that it's all about judging how little you can get away with throughout game. I've got 70k on hook and 190k on wiggle.
