Shop no longer snaps to grid is a bit weird.
Text is unreadable at night; Maybe try making text become white at night and swap to black during day.
Might be nice if Upgrading the shop also upgraded existing buildings of that type.
First tier of traps break almost instantly you could probaly just make them indestructible and just let the uses need to be reset.
Still don'dt know how the blue orb works if its a passive upgrade to all, a Aoe or if you have to put it over the orange one.
The couch and toilet are super cute, might be fun to add a rug but make anything like traps hidden from the ai, and just leave a soft out line of the trap for the player to see.
