I enjoyed the game overall, it was a very fun concept and tie in between cats and dogs. Especially the making biscuits as a cat animation was very fun. The audio was nice and on theme, felt like it made sense, though there could have been too much barking? Maybe not, i was in the zone.
I did seem to encounter a rounding bug i assume where the cost was 11, i seemed to have 11 but i couldn't buy the upgrade (until i had more biscuits, then it worked.
Overall i had fun, but here are some ideas on how to improve! I would like a better distinction between waves, i thought i was still in the tutorial or wave 1 but then i look up and it was wave 5. I didn't realize this was a health is currency type game until I died, so having this mechanic be more clear in the tutorial, maybe a dog comes up and there are no defense, takes biscuit and animated health going down. when i died i just restarted which felt rash, would be nice for it to be more of a pause - oh no u died, try again, type thing
Lastly, i liked the kneading biscuits type thing to make the currency and i like that is was a spend the biscuits, get low on health but go upgrade to be stronger, but i did not really enjoy the kneading minigame after 20 seconds. something more dynamic would be fun! very chill tower defense, nice work team!
