Hidden Red Ball 4 Secrets?

[badipe]

Hi everyone,

I've been playing red ball 4 secrets and I feel like there are hidden things I haven't discovered yet.

Some platformers have easter eggs, secret areas, or alternative paths that make the game even more interesting. Do you know if Red Ball 4 has any cool secrets tucked away in its levels?

If yes, please share so others can enjoy them too. Finding hidden details is one of the most rewarding parts of gaming for me.

Thanks in advance.
