A little simulator I created. It's not that good but you can play it.
Description
Sorry for the bad sprites. I can't draw them.
Controls:
-Esc for exiting credits and exiting the game
-Tap on the outlines for opening the upgrade menu
-DONT USE F1 IN THE GAME! IT WILL RESET YOUR SAVEGAME FILE (except you want to restart)
-Use F2 to activate a effect
