Heeey! It's Portal, but top-down! :D
I loved this game, especially since I'm a fan of Portal series, and I like puzzle games like this. Great usage of the theme, actually; and the puzzles were pretty clever...
Currently some jankiness is holding this game back. The most major one is the physics, or rather, the lack thereof. I found pushing the cylinders *barrels* more reliable than grabbing them, and even then, I sometimes accidentally bumped them off - got a pretty narrow escape from chamber 5 (5A? The one with the OR switch... also it is sandwiched between chamber 6 and 6A, but that is a minor detail...)
I got locked out on chamber 6A (The one with 3 gates, which have their buttons grated off along with the cube & 2 barrels). The rightmost door, when I open it, does not let me pass the barrel for some reason... Is this a bug, or I'm missing something? - I tried posting a screenshot here, but got a token error from Itch.io...
Anyways, apart from that, I'm curious how much you'll develop this game further.
Cheers!
