The resources are too limited for the duration of the game. For example, 900 resources is quite hard to get to get the ammo upgrade in order to just survive. So it's hard to preserve the other buildings in order to get any sort of usefulness out of it.
Played this a couple of times...A few things it could use:
1) Leaderboard would be cool.
2) The arties shooting behind the tanks is annoying. Some shots should land in front of the tanks, others should land behind as well as some landing on top of it while the enemy tanks are moving.
3) If there is an enemy tank right in front of the arty, the arty shouldn't be trying to shoot the tank miles away. It should be shooting the one in front of it.
Got to the end...

Pretty much after lvl 4 I was building the big defensive turrents and covered about 80% of the map by round 25.
Really a fun and easy sling game. I really like the orbital re-entry. Controls for flapping not immediately obvious. Needs network-based score instead of just "best on this PC" as is currently there. Great series of animation for deaths - forks, in food, crater. Make a 1.1 / 2.0 for sure! 5/5
Pretty decent game. Bosses were decent enough for a mini game. Last level is easy enough if you sit just outside the border of the guard and hit with the sword. Ammo was a little hard to get so I couldn't use the gun as much as I'd like to explore the different rounds.
actually interesting game...only thing is on a respawn there should be a short countdown timer since the arrow key could still be depressed from the previous level or spawn.
