I do love this type of game! And a brilliant choice to make for a jam. You fit a lot in with the upgrades system. I appreciate that there are rewards for defeating bosses and for losing, because I certainly did one more than the other. :D
Being able to set the speed of the game was very helpful, I needed to play on the lowest setting to have a chance. Having an auto-click option is also greatly appreciated, however I found it wasn't triggering nearly often enough once things got hectic. When things got really hectic even mashing the mouse button myself wasn't enough.
I managed to get to a point where I had all the upgrades by wave 15 but I wasn't able to defeat that boss even so. Please give me more power! Or else I'll have to install an auto-clicker...
