It seems like we got a similar idea ;) The game is really nice to play I liked the fact that there are some no-build zone as it constraints to think more to find a solution ! You got really fun mechanics however if there is one thing missing, it is some nice looking art and some sound effects ! That is something you can improve later and i you don't know how, I personally learnt how to make basic pixel art from the internet but I think you can learn anything using it so good luck for this ! Great job also I really like the name Bob ;)
