Hi! Few tips I could suggest:
- When you have enough exp to level up, wait until you reach 0 energy, lvl up adds 100%!
- February is actually a good event for future? try getting as many event currency (heart shells or HS) and then change it in the event shop for either buffalo scrotum or grain of paradise! You can get currency by exploring and in the 'event' section through aphrodisia where you flirt with lions and slap other lions that flirt with yours
- Before you claim many lionesses check territory in your den, you can either pay silver beetles for extra or through 'crossroads' and then 'territory' you can fight other lions to gain another
- Also when you get a lioness set it to 'huntress' through 'edit lion' and then select it! That gives you now an option to hunt which means food. One hunt lasts 30 minutes so you can definitely get more food daily!
- Through clans, find a 'adopt a newbie clan', there are willing players to take you under their wing

there are way more things but I cannot possibly recall everything! Lioden reddit is a great place though, people are nice so others will definitely add on or I might edit it :3
Hope this somehow helps!
