Thanks! Glad you liked the mechanics!
You may be right on the gravity; I ended up upping the framerate/game timing midway through development, so I might have forgot to readjust how jumping/gravity feels. Hopefully it's still passable!
And yeah, Windows Defender has been false-flagging anything made in Clickteam Fusion lately. I'll probably just remove the first file, since the uncompressed one seems to fare better with that.
