First to win! (Well, after the author).
Physics are still a little off. A gentle tap should never send the ball screaming off, and moving at high speeds sometimes the balls go through each other without bouncing.
Really bad AI- Gives the unblockable ability to defenders, and will always block all the attacks it can, rather than let the trash through and stop the heavies.
Well done Zelda clone- But the top tier equipment is overpriced and takes forever to buy. 10 hours for a first runthrough is about right, for an experienced gamer.
Grammar issues throughout, and needs more interactivity. Either more different types of point defense/different types of drone, or a main gun that is more than a glorified flak cannon in usage.
kyuubi90: You only need the full elastic and launcher upgrades. Get a good first day, then buy parachutes and/or one direction of thruster as you upgrade the launcher. Fire up, hit the top, bounce off of any really nearby platforms, then drop the parachute and glide off to one direction. When you hit another platform, repeat. If you have fuel left when you settle on the ground, just burn it in the direction you last moved- the timer won't stop until you run out of fuel or stop thrusting.
You get more bang for your buck if you don't buy lesser steps, but you need to boost your height and time, and maneuverability to get more money.
Upgrades are standard TD fare see if you can make them unneeded- needs to spend money on placing a tower, not on clicking it in the menu. Sell option would be nice, as would more variety in enemies- speed, vulnerabilities, immunities. An option for tower logic would be nice as well- right now they lock on to the first target in range and don't change targets even if another one becomes closest in range. A way of changing that for each tower would be nice. (First, weakest, strongest, last, with an option for locking on)
Flaky controls... In a fighting game you should never fail to get a combo off because you entered it too quickly. When I can hit the combo too quickly with one finger there's something wrong.
