Hey, is there a place I can report bugs? I've ran into a few and am not sure of the best way to let the developer know.

someone knows how to open the red doors?

Bravo... PLN this is the currency you need to add!!!

Hey Is it a metroidvania game?

Hey there dev, I'll probably feature this game on my channel if it's as challenging as I hope. But you'll really do yourself some justice by adding achievements to encourage more people to buy it. Don't even be fancy - a single "beat the game" achievement will do if you don't feel too creative. I hope this game will meet my expectations so I can spread the word. All the best to you and good luck ...
