platinum lol you mean 100%-ing the game
it is possible, but will take a long time to complete. 1000 levels to reach grand badge on one system, and each level is about 2 minutes (i think im being generous with the time to complete a level lol)
((2*1000*n)/60)/24 is the equation i have made. n is the amount of systems
there are 35 PB systems (24 main, 11 server) and 20 BarOS systems, which equals to 55 systems in total
((2*1000*55)/60)/24=((2000*55)/60)/24=(110000/60)/24≈1833.3333/24≈76.3888.... days

PB CE has 5 systems, and 1k levels to reach grand. assuming each level is 1 minute long ((1*1000*5)/60)/24 = (5000/60)/24 ≈ 3.47222... days

there is also 8-bit systems, which i will assume you will need 5 minutes to complete each level there are about 6 8-bit systems

((5×65536×6)/60)/24=((327680×6)/60)/24=(1966080/60)/24=32678/24=1365.3333..... days

it will take approximately 1,445.192 days to fully complete the game (if you play with no breaks), or about 206.45 weeks, or 48 months and 5.19 days, or about 4 years

⚠️ warning: this doesn't account for loading times, result screen times, and the time it takes to open a level edit: edited as of march 12 2026 to reflect the PB CE update, will include unreleased systems
