Adorable! At first I thought you needed to build the highest possible kitty tower, but after it clicked I was building towers as quickly as possible. Well done, great artwork and music too!
I think it happened during the tongue attack. The tongue didn't come out of the big alien in the middle's mouth. The mouth just stayed open. The big alien kept spinning. I hope that helps!
This was super fun! We had three people playing on an android tablet. Fun and intuitive. We did see a bug where the green monster glitched out and stopped attacking. It's mouth was stuck half open. Otherwise, great work!
