I'm suprised everyone said it was easy. It's easy to win, but it's hard to master. (although Mr. Nothing was quite hard because my rockets didn't work all game.) Just wish the upgrades were more interesting and more spread out over the game.
It is a game. There is skill required to accomplish your goals, and there are choices. It's just extremely short. It'd be better if it were longer (with more content obviously, not just stretching out what's currently there) but for it's length it is a pretty good game.
Weird glitch, I'm stuck on 24, but when i exit to the level select then go back it makes me redo 23 to access 24. Even though 23 keeps it's score record of me finishing.
I poped the final ballon, don't sit inside it, every bit of superbeam that's overlapping does more damage. I just stayed on the bottom of the screen and did fine.
Good basis for a game. Add on some bells and whistles and it'd be really fun. Achievements, practices missions (run 10 double bridges in a row for example). Maybe add a boss (horse archer who rides away from you and you need to chop his arrows for a while until he runs into a fire or pit himself.) Also try to work things out so it's never an auto lose situation.
Also, when your view is in the middle of the field you should still show the lane arrows and let me buy units and place them, even if though they start at the back I want to line them up right.
