most people (including me) will not install a new program just to unpack your game that you uploaded in RAR format, because there’s 100 more games that they can already unpackage because they’re in the ZIP format, which can be unpackaged in any OS without having to install anything.

an alternate format like 7Z or RAR or TAR or TAR.GZ or TAR.BZ2 should not be the only way to download your game, but a bonus so that people who already have the right program can download the game faster than the standard ZIP version.

This game was a bit tough to understand and I ran into a couple of issues:

• For a while I couldn't find the carrying weapon, but found that it only appears when you scroll up which was weird, and when I did use it the blocks wouldn't properly activate the buttons.
• I have no idea how the ranged weapon works, and from my use only seems to work sometimes, just like the melee attack.
• The game over screen buttons don't work, so you have to restart the game to play again.

Other than that there seems to be the makings for some fun gameplay, if the kinks can be worked out :)
