The platforming feels rough, especially the wall jump, as MicketyMike already mentioned. Also, you can go through ceilings and floors with the spider, and completely break the game. I tried it for a while, but I couldn't get very far to be honest. Still, I understand that all of this will be polished over time. Even so, I have enjoyed it :)
P.S. Thanks for making me download Roblox, I've discovered a whole new world :D
