Oh finally I managed pass through main training jump field in level IV. Has some only visual errors ostly, but logic seems to be good.I didnt try all testes yet, but I passed to checkpoint with no big troubles ( hero is good level so he jumpvand run currently to maximum ). I has to try pass with this setup in old levels with adequate hero level and if it will be ok, I will finally close this topic for now and in later versions I do some graphic cosmetic changes.
