It's not that important. We are actually covering the game in BrewOtaku's #004 News-Corner. So maybe there will be a raised interested of an English version in the future — but we do accept that some jokes might lose their sense, while translating.
Yes, there might be interest in your game from English language speakers :)
No, don't do it, if you think it's not worth it :)
No worries... hobby game development takes time. We are sure you might make a few people happy.
Thanks for the compliment, we are working heavily on #004 which is already 2 months late :D
