I made this game a few years ago I think, and was one of the most liked when I started, so I decided to put it here, I recently started working on a new version of it, I'll post it here soon sorry for the lack of a translation in the game, but I found just the game file and it was not enough to change, but I'll try to help a little:
The game has a simple goal, which is to kill all zombies / monsters, etc. .. to get money to buy items, simple.
You control the character with the arrow keys and press the space bar, the character makes an attack.
You can also change the skin of the character by clicking the arrow button in game skin.
