Deep lift is a good game. The one problem was that screen freezing issue. Is only occurred on one board and I cannot remember the exact numbering but the level was the one with the little anenome guy sitting in the middle of the platform where the exit tube was located in the last zone before you got to the repair area. The problem reoccurred a couple times, but this last time it occurred later and the diver was able to pass the anenome and the second his feet touched the platform the screen jumped to reveal the exit tube.

I only am writing this message because you seem interested in quality control which is a very rare concern on this site at least. Once again good game, the fatc that you could not backtrack added a level of difficulty that was welcomed. My only suggestion for a substantive change would be to have less lives available during the game.
