This game looks, sounds and plays out great! Just wish there were indicators for how much the doors affect jump, platform movement etc.
Also not sure what the light doors do?
you might be referring to the charging gate mechanic. You need to hold down the spacebar to charge the gate, and the duration of your hold determines how long the object will operate after release. This is actually an intended feature, not a bug. If I've understood correctly, I hope you'll give the game another try!-_<
