There's a bug with the big slimes. sometimes when you hit them they sink into the floor and either go offscreen or get stuck in the wall. Also when looking at the stats for each child they're stuck at 0 days old and their screen duplicates itself and flickers a lot. Great game otherwise!
The slimes will be reworked, alongside the other enemies, in the next updates. I know that the current enemy AI and behaviour are subpar, but I will work on those. When it comes to offspring stats, those were just a stub that has now been expanded in the 0.3.8 update, which is currently being tested by supporters ^^
