Not a bad time to sub at all. I only just found the game and subbed earlier this week. Don't be too modest, your game is worth it.
Thanks for supporting and for the kind words! :D
It's just a bad time because of how the monthly payment is set up. If you pledge today, you will be charged the same amount again on February 1st. ( So you'll only have the benefit of the pledge for like 2 days in the case of early access ) but if you pledge on feb 1st you'll get access for the whole month and be charged again on march 1st.
If you pledge to the " goodies " tier you don't lose much though, because you'd get the PSDs/Sketches for January in 2 days on feb 1st. Which value-wise is normal! :)
