I got a chance to check out your playthrough, awesome stream!! Thanks so much for giving the game a go, super happy to hear you had fun!
I already got some improvements cooking away in the kitchen:
Enemies now get stronger with more health after each round and continue to grow in numbers too. The main appliance towers can now level up by getting XP from damaging enemies. I may experiment with giving each of them an added feature when they reach level 5 like extra projectiles fired or a new attribute like random crits, enemy slow down in radius, etc. Each mobile tower now has their own unique buildable/upgradeable tower that have a fun kitchen theme.
I'll get straight to work on new, interesting enemies that are lesser in numbers but can take a beating. I can try cooking up a new map layout after I get these previous changes updated into the game!
