Stack Attack for Flipper Zero

Stack Attack, rebuilt to feel like when you were at school playing it on your Siemens (C35, C45, A50, M50 and others had it built in).

How to play

You know how to play, don't you?

Button	Action
Left / Right	Walk, push a crate
Up or OK	Jump
Back	Pause (Continue, Options, Menu)
Hold Back	Quit

Two modes: Original and Fast.

Modern perks: LED and a bit more modern vibro. Both, as well as sound, can be switched off in Options.

About this remake

This is a fan remake written from scratch. No code from the original was used: the rules, timings, graphics and sounds were reconstructed from gameplay of a real phone and from other open-source remakes. It is not affiliated with or endorsed by Siemens.

Credits

• Original game: Siemens.
• Rules and sound timings cross-checked with eaun01re/stktk, a remake built by watching the original.
• Reference footage: Siemens C45 gameplay and an Android demake.
• Heap Defence, the earlier Flipper take on the game.

Boring technical details

• Original runs at 15 frames per second with one crane, like the phone; Fast runs at 20 with two. Every cleared row adds a crane, up to 5.
• Score: 2 points per crate a crane drops, 10 times the number of cranes for a cleared row.
• Settings and high scores are saved to /ext/apps_data/stack_attack/.

Building

ufbt                  # build
ufbt launch           # build, install and run on a connected Flipper

Graphics live as ASCII art in art/; after editing them run python3 tools/gen_sprites.py. The game logic (game.c) and renderer (render.c) have no Flipper dependencies and run on a computer:

cc -I. tests/test_game.c game.c -o /tmp/t && /tmp/t          # rule tests
cc -I. tests/preview.c game.c render.c -o /tmp/p && /tmp/p .  # renders frames as PBM
