From a pure gameplay perspective Greenhouse is one of the best Game & Watch games. The gameplay is super simple while having some complexity and being addictive. In this game, you play as Mr. Game & Watch and you try to defend the plants from caterpillar-like animals and spiders. Shooting the caterpillars make them disappear completely (should mention they only spawn on the top screen), but shooting spiders makes them push back a bit and need several hits to kill (they only spawn on the bottom screen) which leaves the game to become like a juggling act. Do you hit the Spiders a lot of time at once, but cause the Caterpillars to go closer to the plants or hit them once, but they don't die and deal with the Caterpillars now. For this reason, the gameplay is really good.

However, what kills the game is for me is the fact the dying and gaining a life sound effects are AWFUL, they might be the worst I've ever heard in gaming so far. They screech loud and as someone whom is hearing impaired on my left side and is noise sensitive it sucks. Half of a Game & Watch game is hearing the beeps and the boops, but I feel like I should turn this to be muted as this could be dangerous. If you're in a car playing this game while someone is next to you or you're behind them the sudden screech could distract them causing injuries. My only other complaint with this game is the fact it does become a bit too repetitive at points especially since Game B is the same as Game A, but starts slightly later on.

Overall, I love this game's gameplay, but I feel like the loud screeches really kills the mood and I wish it had different SEs otherwise this would be my favourite Game&Watch game I've played thus far.
