an obstacle rather than to entertain us.
I could only be arsed playing through 'normal' mode. I felt that the earlier levels were a bit too samey - having no traps other than static walls - and though there were some great ideas - I loved the 'frogger'-type level and the idea of the circles that unlock things - I kinda felt there were too many levels that were just put up as an obstacle rather than to entertain us.
Maybe it's just not my kind of game, but I'd like a bit more variety in levels I play and more emphasis on varied fun rather than 'hard fun' as it were.
Also, a record of lives lost and time taken would be cool.
The levels actually looked rather nice when you introduced the circular walls, but graphic design could have been far improved.
About half-way through, I got really frustrated and just cheated through the remainder of the levels.
The tutorial 'broke' when I first hit a wall - the circle started appearing INSIDE the wall and I needed to restart the game. Trying the classic mode on pro proved too hard and I needed to restart to try an easier difficulty. Trying on Noob, I couldn't work out how to win (I collected all collectibles and nothing happened...).
You've got some good ideas here, but I think you need to polish it all a bit, maybe make the game more player-friendly.
