I really loved the concept of dragging the resources into the slots to expend them and gain more power for a period, awesome job

Cool game! I enjoyed playing up until I had too many enemies and lagged out! Think my score was around 5k. I really wanted to get to a diamond and got it. :) I appreciated the AutoMode! 

First and foremost, congratulations on your participation in the game jam, And here is my feedback:

1- At first glance, I thought the mouse would be the primary game control, but I was confused by automode and arrow key control.

2- I'm not sure if I should place the orbs on player, enemies, or specific slots?.

3- Adding more sounds and visual effects will improve the game even more.

4- The UI is simple but could be more polished (no harm, I didn't have time to improve our entry either, but it's just as important as other game design elements).

Best wishes.
