Polymino's versus mode, Junk Attack, is still being developed and isn't quite ready for the public yet. In the meantime, I've also made some unrelated improvements and fixes since v0.4B, which are included in this update. Before I go over the changes, don't forget that you can help improve Junk Attack and get your name in Polymino's credits by joining the Discord server and participating in the playtesting sessions I host there!
