Tips: If you already have played Sonny, you should already know that attacking the weaker enemies (which can get quite annoying) is better than going for the stronger ones.
Level 25 is so easy.

Dashing out some enemies with Area Bursters in the beginning, and cutting off the remaining enemies with a Sniper enhanced with 2 FRBers (and, optionally, a dash of DBer(s) for the Sniper and/or some A-G towers mid-to-end level) to maximize your destruction level.
There needs to be nodes, things that help teleport units connected to it (for example, unit A is connected to unit B, if unit A teleports, at the same distance from unit A, unit B teleports to unit A). Also a Bullet Chargor (charges up bullets that enter its range, even after the bullet exits the range. Like all units, bullets would pass through them except for enemy bullets which takes damage unenhanced)
It's about as awesome to buy as a full version, +3 and +2 for well-made gameplay, but -2 for the fact leveling up is indeed a pain to rapid click just so you don't get freeze'd
A strategy to go at far places: Shoot up, but not too high, usually a few above diagonal. Use your boost (rocket, jetpack, etc.) before falling and when out, keep your height using items to avoid ground and keep most of your speed.
And then after that, the repopulated humans made a nuke to destroy the mad scientist that created this, but were left with a few zombies and blew the face of the mother-flipping Earth. Now one human is left, and mutants (some zombies too). Hurray.
Knightmare Tower is the result of combining IntoSpace! (it gives the game it's vertical upthrow, Burrito Bison is horizontal, yet this shares with the game no other features :P), Burrito Bison (rocket slams=downward cuts) and old princess-kidnapping tales!
Solipskier is frustrating at high speeds, although you can still get a good combo by simply getting a higher multiplier, passing through tunnels at high speeds, or both! That will rack your score up like I did.
Halolover, This game has no potential therefore it doesn't need any badges no matter what. If you want to find a game with badges find a game that's worth activity. You can't just gain points for waiting.
@pokefreak27 "Why he doesn't just walk beats me." Well if he walked all the police would get him, yeah he might be good for one cop but 1000s of cops is just too much. >.>
