update 1.1 is out now, lots of your feedback has been added.
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.
Balancing note you could probaly make copper traps cheaper like 50 as they not that great till you put a orb on them and add a few more tiers of trap. Silver could be more uses and lets it kill warewoolfs, gold it has more uses and makes money on kill , and platnum could regenerates uses slowly and to adjacent traps ontop of having most uses.
