Please stop the MVP, fail fast, etc. garbage. It's the stage where winners are made. 99% of projects won't sell themselves and you will only end up with the self-pleasing excuse that your idea was flawed when in reality, you've sucked at marketing.
Bonus: It's 2022 and people are no longer interested in playing with half-baked MVPs. Think twice before skimping on a decent UI, etc. There won't be a second chance to make a first impression.
