Pretty challenging! Fall damage, spikes and goomba's that shoot bullets. I felt like the bombs weren't that adequate of a weapon. Timing and placement had to be precise and the damage radius was very small. Limited bombs made it even harder. I think I would have liked this better if the enemies could only fire horizontally on the very first level.
I got about halfway through level 2.
Being able to play in browser is always nice.
The platformer mechanics were pretty standard, but solid. I didn't encounter any bugs or anything.
Do you have any plans for tutorials in Unity or Unreal Engine?
