Jump needs tweaking cause feels weird sometimes. Like in a dream you never actually die so the game is holding on that concept but since it's my second game i have no idea how to sell a good background story yet :/ about 3rd scene if you wait 15 seconds the above plataform comes down. I will continue this game from scratch some day tweaking the bad stuff and make it right, really appreciate your comment c:
Like I said, its a good attempt. There is so much in making a platforming game that it will take long to nail everything. Just keep building more on top of what you have had so far. From now you could try with changing jump height when hold down button, adding momentum, tweaking fall gravity etc. I like your attitude, keep it up man!
