such an interesting entry... really ambitious on the mechanics and it could be odd with the 2.5d to know exactly where the spider was going to attempt to go next with the jumps... I seemed to manage to trap myself (in the picture posted) I couldn't get up here and think I had messed up the machine above, to not get past the path to the right... I think if I was rating just on potential it might be my favourite entry, but feels like it needs a little bit more finessing before it becomes what it can become... I hope you continue with this game because more work could raise this from very good to a truly great game.
Please take my criticism about lack of polish in the spirit it is intended... because the fact you managed to get such a complex mechanic (mostly) working in a Jam is seriously impressive.
