Icy Tower 1.0, the 2001 release

22 December 2001 is the date icy.pl prints on the first public package, and it is the date the English Wikipedia uses for the freeware debut. The German version table agrees. I treat that day as the start of the Windows game.

A zip, not a setup wizard

icy.pl calls the file icytower1.0_package.zip and lists it at 1.73 MB. MyAbandonware’s pre-installed copy is described as about 2 MB. There is no setup.exe in that first drop. You unpack a folder and run the game. That is already different from 1.1, which arrived as an 1.8 MB installer a few weeks later, on 11 January 2002.

Inside, the engine is the same family the later notes name: C with the Allegro library, a Windows keyboard, a tower with no roof. Harold the Homeboy is the protagonist named in later store text. The general classic-game character list does not establish the precise 1.0 roster. Skins are absent. Profiles are absent. Replay files are absent. Record files, the binary logs that 1.1 added, are absent too. If a download claims to be 1.0 and it offers a replay browser, it is a newer tree with an old label.

What players still had

The fantasy of the game was already whole. Run, jump, bounce off the walls, watch the shaft start to scroll once you clear the opening floors. The inspiration Wikipedia cites is Xjump, another vertical platformer, but the icy ledges and the combo shouts are this game’s own voice. Nothing in the 1.0 notes mentions a debug.me file. That switch is documented for 1.1. Nothing mentions fun.mode.on. That file is a 1.2 idea. So a museum install of the first zip is the quiet version: no secret modes, no custom hats, no video of your run.

Where a copy lives now

I point at two shelves. MyAbandonware labels a Version 1.0 package. icy.pl’s download centre still lists “Icy Tower 1.0 Package” with the December 2001 stamp. The archive.org item that people confuse with “the original” is a later RAR named for the 1.3 installer. I do not send 1.0 seekers there. Modern Windows may need a compatibility layer or an old virtual machine; the publishers of those archives do not certify Windows 11.

The 2026 Steam game is not a patch you apply on top of this zip. It is a separate purchase. If you want the first public Harold, you want this package, then you read forward to 1.3.1 only when you care about mods.
