This game was great. I loved the visuals and the polish was complete. I liked the alien UI that changed to English when hovered. The simple gameplay loop of feed creatures their favourite food, capture a new creature, start a new day was very well executed.
I played it for a while, but as it had no end goal the latter part dragged on a bit. I got the first two zoo upgrades quite quickly and then after that there didn't seem to be an end goal apart from to keep collecting. I was getting more than enough money each day to feed the zoo creatures.
The sound was great too, but after playing for a while the looped music was a bit too repetitive.
I loved the minigame to capture the creatures, it was executed really well. I also loved the cute names you randomly generated for them.
There were a couple of bugs throughout. I came across the one mentioned where my creatures kept turning into each other, which was a bit confusing. I also got confused at the start about how many times you were allowed to feed them. I think if they are at 100 welfare you can't feed them any more, but if they are at 90 you can give them their favourite food to get them to 110. I was gaming this by giving them less favoured food to get them to 90 then boosting them up to 110.
Great game overall. If it had a longer game play loop it would be sellable!
