What is the difference between the web version and paid version?
"Note: Browser version is free, buying unlocks offline version download and future updates"
It just gives you a way to play the game offline and supports its creator.
Paid version doesn't push my CPU temp to high 60s. Likely a config issue on my end, but since I bought the game tracking down the issue isn't worth my time.
