Thank you for the feedback!
Will display version number on title screen from next update.
The things that drains health faster is actually acid not slime. I initially planned an immortal slime enemy that will chase you to a certain distance but scrapped because the drawing turned out really bad.
When you think about dragon, medieval theme comes first in mind. So in future if I made a game with such theme will add enemies accordingly.
Have no plans of adding Giant worms as I have already added smaller worms. You are right! There can't be a pyramid without mummies but they will added in the update after upcoming one.
The levels can be completed faster once you have purchased the teleportation device which I planned to keep expensive to avoid exploitation of this feature.
I have already taken care of jump controls. Will make the controls more simpler once update 0.3 is launched. Reason being this game will be ported to android device so it's will be easier for me to add UI.
After reading the review about level 15, I think I need to redo level 15 and 21 as 21 is shorter than all of the levels. For the time being I will keep the old layout and redesign in update 0.3.
I got help the needed for dialogues with sister. That person have really written spicy dialogues for different scenarios. Far better than three repetitive dialogues I have written.
