Catch the Butterfly

How do you even play the game :/ ?

All instructions are in the description.

To launch it, open .bat file.

This game is endless.

i cant start the game but the movement keys are not working

Are there any java exceptions?

You start from top-left corner, so, move down or right first.

Some of these are definitely impossible to catch, but just holding down Space helps a lot :P I keep thinking the background is a Magic Eye picture!

I kept trying but couldn't start the game. Best I got was the following errors:

Pressing A did nothing on me :( I couldn't start the game.

@Persimmon Pomelo, use Java 8.

@Gord10, are there any exceptions?

I could play it... a nice simple butterfly catching game.
Is it part of the difficulty setting that there are longer intervals of almost no butterflies at higher levels? And is it also intended for the stage number to flicker between two numbers for a short while?

@kfischer_okarin, butterfly generation is random, so level does not affect it.

Level number flickering creates a mid level speed between levels.

I fear this doesn't work on Linux Mint with default package sources yet. As you wrote, it requires Java 8, but the best you can get from the package manager is openjdk 7.
So sorry, couldn't play it :/

@tinyworlds, there is an non open source VM, that is downloadable from Oracle`s site, isn`t it?
