As I hit level 10 it felt like I had all the towers I had upgraded about as far as I needed, then I started getting swamped and couldn't do enough before I was simply mowed dowm (literaly). I had some 30,000 nature points, but hadn't needed them until that very second when things went from in control to wildly out of control and deteriorating quickly.
BTW, the sun god SUCKS ASS. It should seriously be more of a burst fire nuke everything instead of a medium fire rate, high damage tower that activates sometimes. I expected more of it.
Controls suck. I'm not entirely sure what they do, but it looks like it adds a certain amount to my absolute value of my velocity in that axis (i.e. if i'm going 100 px per second down and hit up, I'll go 110 px per second up, regardless of horizontal velocity).
Not enough choices. The board is the size of your standard match-three game, however, most of the information is useless. And any time I spend looking at the ramifications of my choice is time spent not picking turnips, thus causing me to not surpass that 500 points per level goal.
Not to mention that if at the end of level 2 I have 1580 points, the goal for level 3 is 1500. I need not do work and any work I do will make the next levels easier.
The maps don't seem to be made such that you can actually run through them very easily. There were numberous locations where I'd come down and have no forward momentum and be at the base of another jump.
Also, the bike exploding violently is unnessessary. It shouldn't happen and made me think--the first time it happened--"oh shit, that's going to cost a lot of money" and then it didn't.
Games need an indeterminant outcome as decided by the player. This has two choices:
Death or Continue playing followed by another choice:
Death or Coninue playing.
That *barely*qualifies as a game.
