Thank you so much, that really means a lot! Glad you had fun.
You’re right about the lag, and thanks for flagging it. The late game gets heavy: the bosses get huge, and with weather, night effects and a big army on screen, the game has a lot to draw each frame. I’m working on making the late game lighter for the next update.
If you don’t mind, which browser and device were you on, and roughly how far in did it start? That would help me track it down.
Thanks for playing!
