Old school KnP, CnC, and MMF user here (I used to frequent #k&p on DalNet well over a decade ago) and I'm loving Construct 2.
Just wanted to share a small demo platformer I made tonight. There really isn't any point to the game yet as it is just a proof of concept. The only bug I ran into was when the character sprite would run into a one of the 20x20 squares that makes up the floor. If I walked into the side of it at full speed, the character would drop right through the floor. I made the 40x40 squares instead, since the character is 20x40.
Check it out here :
Arrow keys move the character, shift jumps, and left/right clicks summon the portals!
Let me know what you think!
