In sector 3, after the 3rd node (regular battle), when trying to move to the next one the implant-in-inventory confirmation box just stays there and can't be closed.
I can't replace the implant because the implant-replacement confirmation box buttons also don't register the choice.
I tried both nodes after reloading and continuing but the problem remains.
The buttons are gray, instead of green and red in those screens.
Otherwise great game! I quite enjoyed it. Nice graphics, the music can get slightly repetitive after some time but it sets the right urban atmosphere. The battle mechanics have some nuances that allow for some deeper strategic gameplay, they seem well thought.
Edit: I tried starting a new game but pressing continue loads the old save (I'd just finished the first boss and entered the second stage when I reloaded). When does the game save?
