Awesome, until getting the x1000 combo is the last trophy you need for the achievement despite the fact you've already gotten the x1000 combo four times in a single game and still no trophy.
Apparently the reward for the Legendary Firearms achievement is that you're no longer allowed to shoot, reload, or switch weapons. Yay bugs! Also, the game is too short.
It'd be nice if there was an animation or something showing that you were swapping places with another player, instead of suddenly being the wrong color and your apparently controls not working (and then "All human players are destroyed").
Tip: Before moving to another store, sell your entire stock. Losing 50 CDs when you buy the next store (and not even being able to move back to retrieve them) really sucks.
The keyboard doesn't always work. It seems that even though I just clicked the "Back" button when pausing, the keyboard doesn't work until I click again. Also, it's always fun to come back from pausing and not be able to stop running to the right.
If I had known all these years that pinkeye gave you laser vision, I would've shared more microscopes with the kids wearing gauze eye patches in school.
Jumping on slants needs a lot of work. It makes the game a little difficult if you don't know if you're going to jump forward up the slant or jump back onto the next higher object. Or when facing away from the slant, it's always fun to randomly jump straight back into a past self instead of forward like you meant to. I especially liked the part where I wall jumped straight up four times in a row instead of actually having to go back and forth. It saves a lot of time, if you can figure out how to do it on purpose. Don't expect a fix to ever be done. The sequel is already on ArmorGames and the jumping on slants (especially the unpredictability of jumping off walls simply because you're standing in front of one) gets far worse.
The walkthrough is terrible... nobody wants to sit through 14 minutes of a YouTube video just to figure out where on the "keyboard" Ode to Joy is meant to be played.
Pulga, the three games you uploaded are not different games. They are all the same game (with the same bugs). The only difference is the controls. Please remove two of them and give the third an Options menu. And fix the bugs.
