Very nice main menu and I really liked the way you interacted with it but felt it wasn't very intuitive and using W/S or the mouse instead or as well would have been much better, I also really like the music for the game and gives it a fun vibe but I thought it was a little too quiet.
I don't like how the game close itself when you die and felt as if the you've died popup could have been a little nicer and the same goes for the winning popup.
The running animation for the player is very nice and smooth but felt as if jump and/or falling could have used an animation and a SFX and although you don't get to stand around very much an idle animation would also have been good.
The jumping levels seem a little odd but are fun and the running levels are good and I quite like the animations for the big guys chasing you and the change in gameplay from level to level makes it quite nice and it doesn't feel too repetitive.
I found this game to be really fun and liked the main menu, the music also helped with this but feel as though the jumping levels felt out of place, they also made for a nice change of pace between levels. However the game could have done with some SFX and the pop ups weren't very nice but besides that a good game.
