DRM-Free and Steam Key

All users that purchase this title on Playism will receive both a DRM-free copy and a Steam key!

An indie classically-styled 2D side scrolling action game packed with adventure.

Starring a salaryman (bipedal frog) who collects a variety of weapons, fights outlandish monsters and visits strange lands on his business trips. Beating normal mode unlocks the challenging ZANGYOU (Overtime) mode, newly added as of October 2015.

Fight for your life through a menagerie of unique monsters while getting your hands on exciting new tools of the trade.

The game is also compatible with game controllers, if keyboard controls just aren't working out for you.

  • Zangyou Mode

We released the upgrade of Kero Blaster, "Kero Blaster ZANGYOU Mode" which has more stages than the original, vastly expanding the game. 

  • MEdia Reviews

It's dense and perfectly paced, just begging to be replayed over and over.


Kero Blaster is a magnificent run and gun, colorful, well-designed, offering a great curve of progression.


Another state of the art Studio Pixel retro production.

3D Juegos7.5/10

It's short. Very short. But it's also a great game that those looking for a retro-looking action game should definitely consider.


An excellent run-and-gun shooter that plays beautifully on both PC and mobile; the only sticking point for some players will be its relatively short length.


Regardless of how you may feel about frogs, be sure to give this indie game a try!

In case you experience performance issues while playing the game, the following fixes may help.

If the game does not start up properly

1. Check that the files have been fully extracted.

2. Try installing the latest version of Direct X. (Run contained file dxwebsetup.exe)

3. Try installing Visual C++ runtime (for 32 bit OS specs run "vcredist_x86.exe"; for 64 bit OS specs run vcredist_x64.exe)

4. Try downloading the game itself a second time. There are cases where the game file itself is broken.

If the game is running slowly

1. Try changing the screen size. Window mode can be toggled from the menu screen.

2. Change your Windows screen settings. This can improve performance.

3. Try updating your Windows driver. Performance can be improved by updating drivers related to graphics.

Controls are poorly distributed for the keyboard/controller

You can change the control settings at the menu screen. Under default settings, press ESC to bring up the menu screen.

Game controller is unresponsive

Try starting up the game again without touching any of the buttons on your controller.

Why I cannot play ZANGYOU mode?

You need to beat the game first to play ZANGYOU mode.
