Thanks so much for playing! Yes - I was actually experimenting with the mouse controls yesterday. I have actually been testing mobile play more often and I tend to go back to PC with no gamepad last since I am not normally a PC gamer. currently the enemies drop money, but the "Arena Stickers" are the current in-field power ups and with keyboard you cycle them with q+e and use them with r, but adding mouse attack support would make using them with the mouse more intuitive too. currently i think this system needs to be revamped and play-tested with better power ups that read more easily and have more apparent impacts to gameplay. I'm hoping to get some more good feedback like what you've commented here so I can keep learning what makes a better experience for people who play my games. Thank you for taking the time to help!
