PyWeek - Dragon's Bakery - feedback

Well, after the trouble of installing arcade 2.7 (why use a dev version???) I was disappointed in finding that it was an unfinished game. Could move and shoot, but nothing else happened.

no module arcade.background was found :(

ModuleNotFoundError: No module named 'arcade.background'
:=

I couldn't make it run

dont work

Sadly arcade 2.7.0 is not available via pip (and hence can't be installed with the requirements.txt) and the available release 2.6.5 didn't seem to work.

not working for me it says no module named arcade also tried to get it to work in the terminal but couldn't get it to work there either

The game appears to be unfinished. You have a Metal Gear Chibi purplish guy, chased by a teal Gizmoduck robot guy. He catches up to you unless he doesn't. You're in a building, on Mars I reckon. You can only go in and out through the doors, the robot can go wherever it likes. I couldn't find a "shoot" button, despite there being a "src/weapons/bullets.py", so I don't know, maybe I missed it--it wasn't in (nearly nonexistent) documentation. I gather the author considered this game unfinished and turned it in anyway.

Trying to install requirements.txt with pip results in:

ERROR: Could not find a version that satisfies the requirement arcade>=2.7.0.

I tried changing it to 2.6.15, but that fails with:

I have the requirements installed and I used Python3
