Great game! He has some issues with controls and physics, but he's awesome for a Game Jam project! I also have not gotten used to the fact that the character can not cross the portals. xD
The art is very captivating, with a great color palette and fits with the game and with the jam.
It has a bug in my Windows 10, like several games made in Game Maker, when I put on full screen, the game begins to lag.
If you are going to continue with the project, I recommend studying a little of the level design of Portal 1 and 2 (which are probably your reference). Your level design lives up to the three-dimensional pioneers, however you seem to have stumbled into the problem they struggled to face that is when the player gets stuck. I think a planned level design would be more interesting than a "Reset Level" button.
Hi, thanks for taking the time to play it and also to comment.
Totally agree with you about level design. I had a concept of dropping a box out a chute if one got destroyed, but time got the better of me, and in the end the levels are so short all it broke was the story aspect really. Definitely can be improved on though, as well as adding more uses for the portals. Maybe for a future project.
As for the lag, I've never heard of Gamemaker specific Windows 10 lag, and never experienced it, and I've been using GMS for ages. It only runs at 30fps, and just did a frame test, and it's over 1000fps. The code is pretty simple. If you're getting it on other projects might be something on your rig.
Thanks again for the comments.
