No matter how mad I get I just can't stay mad at this game. That being said this is probably one of the hardest games I ever played but it's a very justified difficulty. The game isn't broken, I just need to get better. Most of the times I died were fair but there were many instances in which I thought I had enough room to squeeze in between the block and the wall but there wasn't. I think the second farthest block should leave enough room for you to get by. Also I feel as if keyboard players are at a major disadvantage because of the free flowing movement. Once i stated using the mouse rather than the keyboard I jumped from about 3-4 triangle to 8-9 triangle. (for those of you that haven't played yet that's a lot) I think the best way to remedy this would be to set the paths and obstacles to a grid. It would've been nice to have more than three lines of instructions. I checked the author's comments and no luck either. Mechanics like "collect this-many-triagnles to advance the level" would've been nice to know. I thought that the triangles were like exp and by gathering 3 every time I would eventually level up. I LOVED the music! it was great and if the collectables would match the beat of the song then I personally would be in heaven. I actually prefer the collecting mode over the avoid mode and I don't see a need to make it an unlockable. (although the idea of unlockables is really cool and I think there should be more. I REALLY appreciated how, for the most part, the triangles were colored differently than the squares and rectangles. That made my life so much easier.
In short I would love to see a grid, more unlockables, more instructions, and the collectable sound synched up with the music in the next update!
