This is top 0.4%. 3538 was top 1% exact. I imagine the feasible limit is a bit above 4k. The hard hump is killing this last fever lizard and then the final bonus poacher for another bonus 300 points. However time is nearly out at this point. You get more points for killing enemies during fever time, but actually trying to avoid killing things is only possible for the very first wave. This is where I got the few points to bump myself from 3538 to 3606. Tried out Ala, but moving Selen around turned out to be better as she has range and can hit lizards that come from top right whereas Ala can't.
