At the moment it would not work with any MV version lower than 1.6. However, I will upload an automatically converted version of this plugin that does appear to work in 1.5.2 (I just tested it). Unfortunately, I can’t promise it will work flawlessly or without any bugs. I can and will provide you support and if you do have bugs or other problems you can email meand we can figure something out. If worst comes to worst and we have no luck on getting a working version for you then you can submit a refund contacting itch support
Good to hear! I hope all works out well for you, but if you get any problems don’t be afraid to contact me through Twitter, Discord, or email. All links are available on my profile page
