I liked this game. It has a increasing difficulty that makes it fun for the surprises of the monsters you face.
The designs of the character and the monsters are the best, although the maps change little. And the weapons are interesting, although a newer does not mean it's necessarily superior.
The music is a bit repetitive, but not annoying.
Reviews for "Rokilot: The New World"
I got to level 12 using only the melee and the shotgun, and only used the shotgun on the very latest levels. Ammunition really wasn't a problem because it regenerated every level and if one gun ran out, you have all the others.
I really like it, but even fully upgraded, I can't seem to get past level 16. There's a lot of red stuff flying my way and it's really hard to avoid it all.
Still, that has to do with me, and like I said, I really like the game.
In response to SonicSteel - This is actually not as profitable as you think. While farming a level over and over has its benefits, as the levels progress, more money can be found (as more monsters are added). The system in the game works fine.
Tip for hard survival:
Kill all enemies except slimes, they will soon bundle up behind you and fill the mob limit.
Although the limit increases every few kills, spawning 2 monsters instead of one, you won't have much trouble taking care of 2 at once while running in circles around the slimes.
If nothing new seems to have spawned, it's all slimes now, so kill a small one and look around.
That was the only way for me to manage over 400 kills in hard survival mode, although it took some time.
