I tried this out but it really isn't for me. I got too frustrated by the poor conveyance and sense in screen 3 with the frog :T
One thing I feel is ABSOLUTELY the wrong choice is X/ESC just dumping you into the title screen is ridiculous. It would not have been so hard to simply put you back to the start of the same map, or even on the LOAD screen rather than the title. The saturation was also a bit on the high side and made my eyes hurt a bit.
