XSQUARE ATARI 3.9.2023

This is a game for ATARI ST mono emulators. It is made with GFA-BASIC
and GBE. It is not tested on a real machine and it is possible, that
it can't be run on it. You can try to run XSQUAREA.PRG or XSQUAREA.GFA
in a GFA BASIC interpreter. XSQUAREA.PRG runs with the emulator hatari
1.8.0 and its built-in EmuTOS-image
(https://hatari.tuxfamily.org/download.html).
GFA BASIC was chosen as programming language to write a program compatible
to EmuTOS. The game can also be run with hataroid and its built-in
EmuTOS-image. hataroid is available for Android devices.
The .LST file was written with the Windows X editor and merged and
compiled with the programs coming with GBE. GBE ran with the operating
system FreeMint 1.19 and the emulator ARAnyM 1.1.0 and the result was
tested with the ATARI emulator hatari 1.8.0.
XSQUAREA.PRG can be played with one player (cursor keys) or two
players (keys: w a s d). You must collect all the flags and avoid
crashing into holes or bottles. You can't navigate on the space
fields and you are invisible on the fields with the question mark.
The moving direction can only be left upwards, right upwards,
left downwards or right downwards.
Xsquare is also one of the BrowserBasic 2.05 games and a DOS
version (2000) also exists.
This game shows a good performance with hatari 1.8.0, if a 8MHZ
ATARI ST mono is chosen. But Omikron Basic seems to run faster
than GFA Basic. The HORISCRO ASM game (2016) written in assembler runs
faster and also seemed to run much faster on a real machine.
