Mechanical and functionaly it works and dose exactly what is says in the title. I'de say as a learning project its great. There were no breaking bugs that I could find and it gives you something to aim for. I would just say for your next project try something with a bit more game play/ chanlenge.

Another change you should really make is having the GUI (Time, Score) in front of the cards, I also found myself being able to select the GUI element. Realy unless I need to interacte with a GUI element I shouldn't be able to.

Upload your next project so we can see how your progressing.

Firstly I'de just like to say that the audio and visuals for this game are fantastic. The low score is only due to the gameplay being broken.

But, I feel like you have neglected some glaring issues with your game player/design. The main being that the player can hit there head on the top of the screen, causing them to fall and making just from higher platfroms imposible. I also found that collecting a cystal mid air also caused this effect.

Secondly, with only a jump input available, i found the task of dodging the incoming hazards more of a case of luck rather then skill. Maybe some left and right movement will give the player more ability to avoid these hazzards.

This game feels like it was pushed to the aesthetics stage of development to early. Resulting is a game that looks and sounds great, but is always going to be draged down by broken gameplay. Try building a bullet proof game out of boxes, then add in your visuals it will result in a must stronger product.

Still looks and sounds great though,
Keep it up.

Not sure if it is just me, but nothing happening here, its just sat at 95% loaded with the construct2 logo?
