So I've been speedrunning this game a bit because I love it. So far my best time is 4:08, and I think I might be able to get under 4 minutes. If you wanna try and beat my time, I started the timer the moment I started moving, and ended it when I touched the escape pod.
Anyways, if you're planning on updating the game, I found a few glitches. As people have already pointed out, you can softlock yourself in a few spots by jumping while halfway up a slope. I've also seen this glitch when jumping into a ledge:
Not sure why this happens, but when I was about to get above (or I guess below) the ledge, it just teleported me to this height, trapping me. I've had it happen in a couple other locations, so I don't think it's this ledge specifically.
On another note, the magnet is a little difficult to control sometimes, like when you're in a 1-block-wide gap::
For example. If I hold the magnet button and go left, which slope will I attach to? i don't have any control over that, which can make it a little annoying to try and get through the later areas quickly.
Aside from that stuff, though, I really like this game. The level design is well done, especially considering that I was able to keep my bearings on my first playthrough even though all of the blocks look identical. The mechanics make for some interesting puzzles, and since your vertical movement is so restricted, you have to try and find ways to get to a specific height so you can progress. The sections where you just fly through open space are great too. There's a bit of irony because even though you're not in an enclosed area, you're still stuck travelling in a straight line, and you can't go explore any of the things you see. I especially like that you can see the escape pod long before the end of the game, it's a nice touch.
Also the music is good
