I'm at level 26 or 27. Leveling up has gotten really slow, and I even have the giraffe equipped. I really wish I didn't power up the strength right away.
And it is a lot better than Alien Homnid, but it has a lot of problems. Enemies just pour down cheap attacks like bombs/arrow/magic that knock you back, which is just annoying, a lot of the time you can't actually see something because the great 2D graphics are blocking your way, and everything feels too flat; by flat I mean that what should make sense doesn't, if only because the sprites aren't lined up.
This game is also another game that would be fun to play while listening to music or a podcast. Just have to find a good area to grind up some levels.
