It would be nice if the game stopped lying to me about saving. I've just lost two days of progress - that's around 2.5 k rubies, lots of new items, a bunch of emeralds and achievements. I get that this is a beta, and I should have backed up to a file, but I thought this was fixed - it happened after a recursive error when I left the dungeon. Otherwise this is an excellent game, but the save issue is a pain.
If you build Banana Investements Advisor (2-4), remember to withdraw your cash when you're at 18k. If you wait until 20k, the Banana Research Facility (4-2) actually has a higher yield. Why? It takes 6 rounds for the BIA to get to 18k (you're a bit over actually), 7 to get to 20k, and the payout for a fully upgraded BRF is 3 k every round. So 18k / 6rounds = 3k, 20k / 7rounds = 2,8k. Makes sense? The BIA is cheaper as well, so it's overall a better choice - just remember to withdraw your cash ;)
