How do you beat stage 20 on this is the only level too

Stage 20 on This is the only level too is solved by going right, under the platform, jumping up onto the platform passed, continuing right while jumping up onto the next platform and then further up onto the left platform. The level continues with making the player jump over the topmost boxlike platform, continuing below the finish passing the spikes and jumping up onto the rightmost bottom platforms via the invisible dito. The player then has to utilize the hidden overhead platforms to pass over the remaining visible platforms thereby landing comfortable on the finish.
