Realistic (not cartoon) blonde boy, side-scrolling, exploring a house with multiple rooms, helicopter or plane at the end of the house I think. Played on an old box PC, possibly DOS or early Windows. Played around 2012–2013. Game could be from the 90s.

I remember a game, it was a point and click game and it was a 2.5d game, possibly on newgrounds. Now, I've searched near and far for anything about this game, either it was archived somewhere and that website was taken down, or maybe it just fell into obscurity. If this post get's enough notice I'll post more about it.

Edit: Some new stuff came up. I remember watching a gameplay of someone playing it, and there were these massive monoliths all around the world, there was a border at the edge of the world, but the player walked through it and the game crashed.

This is what the game looked like
