Incredibly high-effort and good gameplay, there were a lot of collision bugs such as the gate that opens with the portal, and you'll have to get onto the platform. I have a question, where on Earth do you get off from that platform? I just jumped randomly and I phased through walls and landed in a random area, that disoriented me but I managed to win nonetheless.
That bright light when the time is close is rather annoying, you should change it to something more like a light that envelops the planet, but its opacity is low and doesn't have that bright bloom on your face.
The main menu is very polished too.
Although, why on Earth do I have to install the game when it can be played just like the other game by being shared into a zip file? If however you're talking about the size of the game, maybe just add an option for the download to have installer and zipped file.
Nonetheless, it's a good game that has a lot of potential when created into a huge standalone game. :D
