I really love this game! The design is very unique, feel a lot of accomplishment when under my control the correct tower got powered and work! shoot them all!!!
I really like the electric shock effect when you get into water, very intuitive and make you focus on moving as well as planning.
The design for the android tower is clever too! it is nice to see a tower that can "store" electricity in a way, add more strategy. It might be nice if there are towers that can actually store and send out electricity for some levels. would be cool!
The only part that confused me is the bat, it takes me a while to figure out the bat can avoid the bomb and android tower lol. Also it might be helpful if using color or something to differentiate the towers, I got lost which is which even after several levels.
Also the game get back to level 1 when finished? Lol I really want to see a ending page with that.
One minor thing.. I don't like using F as connect and disconnect the cable lol. Maybe space? But this is really minor.
I think the balance of the tower is great, with more kinds of towers and more mechanics/ levels this can be a published game!
Great job! love it!
