Never thought I'd say this, but this is a very simple game about being an alien traveling through space farting at evil business men who, in my opinion, will take over the galactic economy if they are not farted on. I applaud you for your creativity. Here is some feedback if you are interested.

Sound: Background music was good and fit well, but I would have loved to have some sound effects. Like what does an alien fart sound like, and what sound does an evil business man make when he is farted on? Fart sounds could turn this into solid gold!

Variety: This may be out of scope for what you were trying to develop, but I think adding a little bit of variety to the enemies would be nice. Doesn't have to be anything to extreme, just maybe add a slower moving Evil CEO that moves slower, but takes a little bit more gas to eliminate. Little things like that to add some variety to the gameplay.

Constraints: It might be interesting to experiment with some constraints on the gameplay. Right now its move and fart, but farting is unlimited. Perhaps your alien could have a Gas meter that recharges only when you aren't farting, or maybe there are burrito power-ups that could refill the Gas meter because they make you more gassy. You may have to slow down the overall speed or reduce the amount of enemies if you want to try something like that though. Giving players a reason to not just rapid fire fart could make gameplay for interesting.

I hope this feedback was helpful! Thanks for making this game, and keep on making games!

Your title and high-level concept are great. I saw Speed Runnin Santa and I had to click to check it out. I definitely wanted to be a speed running santa; however, here is some feedback.

Sound: As far as I can tell, there is no sound in this at all and that makes me sad. If you have no idea how to make sounds, that's fine, but you should check out some free software for sound generation like SFXR. It's super easy to use and make sounds that would work perfectly for a game like this. Again, this may just be my browser being dumb and not playing the audio, but if that's not the case, you really should think about sound for your next game, or this game if you plan to update it.

UI: My guess is that you have the player press "Z" to start the game because you are hoping they will return to it when they can't figure out how to jump? When it comes to controls, never assume anything about the player. Especially in smaller games like this. I know it can seem like the obvious solution to you, but I promise you that 50% of people won't figure it out. Be more overt about the controls if you can.

Controls: Given that this is meant to be a speed run game, controls are everything. If your controls aren't tight, and consistent it makes people really not enjoy running a game because they don't have the control they want to go fast. I was having a pretty rough time controlling the character and the jump was pretty floaty and difficult to maneuver. I may just suck at this game, but i could only get to like the 4th screen and couldn't make it past the two spike ball things going back and forth. After around 6 attempts at the same area I was just done playing because it seemed impossible.

I hope this feedback was helpful! Thanks for making this game and for giving me the image of santa being a speed runner who collects presents! Keep on making games!
