it's fine, just very uninspired.
Player controls are pretty good, decent visuals along with some cute squash and stretch and nice, simple transitions. But, the lack of visual and gameplay variety really handicaps this game :/
Gameplay is lacking greatly, if this game is "hardcore" than have death be something that actually punishes you. Sure, you get sent back to the start but I found myself dying just to quickly get back to where I was so I didn't have to traverse through it again, and the fact that you keep your collected foods on respawn really makes this game feel monotonous and lacks any sense of fear or triumph.
I got to about halfway through world 2 and the introduced mechanics are just not enough, the controls are simple enough to where you could have really played around with different hazards and interactable objects, but spikes and random white guys thrown together with pizza and cake to collect just wasn't gripping...
Keep trying though! I see this isn't your first game and I'll check out your other stuff, you seem to have the technical know-how, just gotta work on fleshing it out with more fun mechanics! :o)
