This was a stencyl demo, or example pack. Personally, your a big amatuer. you just glitched it rather than changing anything.

Took 2 mins to complete the game and it didn't entertain me at all, i don't know how you are supposed to keep playing for hours on end...
You can just jump over all buildings and monsters and get to the end in no time...
Graphics aren't that good, no music, no menu, buttons aren't intuitive, you can't even use wasd to move, no changes overtime, when you reach the end you just get back to the start without an increased difficulty or whatsoever, monsters are so easy to kill it's just boring, gave it 1 star only because there were no visible bugs/glitches, but that's probably because the game doesn't even seem complete yet.

I actually thought the controls were smooth and it was satisfying t shoot things, but the game is incomplete. There's no title screen, menu, background or any variety in graphics. It's the same walking animation, same alien and the same setting. It gets old fast for various reasons.

Change the controls, add a menu screen, do a little more game testing, perhaps add some background graphics and generally do some enhancing.

The controls were sloppy and the graphics were awful. There was always a delay when one tried to jump, which led to way too many deaths.
