Another Tower Defense Game! I just played Cyber Attack before this, there's some shared DNA between your concepts, definitely check them out. I also made a tower defense game earlier this month, I have been wondering about the viability of this genre a lot lately. Also, my garden is starting to pop off this year, and last year the snails were an absolutely menace, so I can totally relate to this gnome. I installed some anti snail walls to hopefully help slow their invasion this year.
Like this. I do suggest your gnome try them out to protect his mushroom, cabbages, etc.
Great game, good challenge, nice work. :)
