Many yars ago I played a flash game on a dutch website just called "Chomp 1". You controlled a Pacman-like creature with teeth. But there wasn't anything to collect, but to "cut" out by eating away much space possibile. But there were also obstacles such UFOs that make you loose your lives. There was no music, just sound effects of his voice. I tried googling it up and reverse image search, but in vain. I already tried to ask on Reddit, but nobody can find the game yet. There's a thumbnail I found in the website, but nothing more.
