Hey I just tested the beta 4 demo.
Playing this game made me feel like a kid again watching saturday morning cartoons when that was a thing. Some big things that I think that are hard to accomplish here were, that the world feels real and inviting and the game feels fun to play. Nothing is too serious where it feels hardcore but there are spots where it gets intense and you take the game seriously, like jumping off the bouncing bubbles in the waterfall.
A couple of things that I think would make it just perfect in my opinion would be more but "out of the way " fun npc characters that would interact with wink during platforming stages. And also more things that can show us more of winks character like his bedroom. It might be cheap and spoiled of me through nintendo games but I also think the overworld could benefit from signs that say the number of the stage on the sign but not in a text box.
I think after this game Wink should not stop here, I'll be happy to see more of him. And somehow the stages are wink too. When playing I wanted to see everything there was in the stage. It really feels like walking in a neighborhood and interacting with things as you go along.
To mish mash two games together to give you an idea of this game id say Kirby's Deamland and Megaman. And still completely original standing on its own. :)
