I have compiled it on 32 bit system as well.
After a few small problems quick solved on the project's github page, I am gonna build debs.
The 32 bit desktop freeze down a few times, but 64 bit version works fine.
As I checked, the Budgie Desktop consumes:
- 32 bit version ~ 200 MB of RAM
- 64 bit version ~ 400 MB of RAM
An opinion is yours.
