This is actually a very solid idea for a tower defence game, I haven't really seen anything like this before.
Though I think the controls are a bit awkward, given how much micromanaging is involved. It would be nice to have access to the mouse for this.
I like the concept of the tower being able to unfold and fold depending on the circumstances, it seems that the energy levels only recharge if the generator part of the tower is open.
I also would have loved to see some instructions in the game description as it took a little while to figure it out. For anyone else reading:
How to play
- Use arrow keys to select "Play" on main menu, then press space to select it.
- Use the up/down arrow keys to select a section of your tower. Press space to 'fold / unfold' that section of tower. You'll need to do this to align your gun turrets with the enemies as they come in.
- Select the top part of the tower and press space to build new layers, then use arrow keys and space to pick the kind of section.
