Hi and thanks for your feedback
I agree with the graphics ,they can greatly be improved as we don't have graphists in the team...we made the minimal to have a working prototype.
For the moving spikes, you have two way for curling the snake, zig zag and jumps...with a good jump timing and jumps it can be done. But i agree it is not the easiest part of the game, i think it's the more difficult and there is no more difficulties after.(almost the end)
And as you said the first room was easy, the second less, and that's the prurpose of the snake mechanics, simple things becomes harder once you grows. The game isn't probably well balanced, we worked one week only on the game. The main goal is to have feedbacks, and perhaps in the future make a complete game...
For the safe point heal, i agree with you. Only eggs heal the snake, and i didn't notice it wasn't enough.
Thanks for playing ;)
