My overall thoughts and feelings
Gameplay - The gameplay is perfectly suited for use on a mobile platform, with simple and intuitive controls for ease of use while also allowing for the use of a mouse to play. As the game is so simple, it really allows for a pick up and play experience, which is doubled by fun and a slowly increasing difficulty level which allows for a somewhat challenging experience. Planet Panic feels inspired by older arcade games, as the game lasts as long as the player is able to protect their planets. This also helps to add a lot of replayability to the game as players will want to replay to see if they can beat their previous scores. The gameplay is fun and is a breath of fresh air in an otherwise oversaturated market full of first person shooters and battle royale games. However one flaw which I noticed is how easy it can be to maintain one planet until more re-appear. In terms of a solution for this, potential increasing the size and frequency of the meteors as more planets are destroyed, or as more points are gained, may help to resolve this. In addition to this, due to the nature of the game, it may be a good idea to add a leaderboard of some sorts, so the user can track their scores and try to beat them.
Look and Sound - The game uses quite a cartoony pixel art style. This is pulled off extremely well and really helps to bring the game together and create an experience unique to the game. The style is familiar while bringing in new elements of design which help to allow the game to really stand out from the crowd.The sound effects are perfect for the feel and aesthetic the game is going for. The sounds are cartoony and somewhat retro sounding, which really matches the pixel art design that is being used. In addition to this, the sounds are clearly distinct from one another, using the correct tones and pitches to convey the action on screen, such as the planet destruction sound using a Minor pitch to convey the negative aspect. The music in the background is also quite lightheaded and reminds me of arcade music. All of these factors really suit the style of the game and matches my prior thoughts in regards to inspiration of arcade titles
Originality - In terms of originality, as mentioned within the gameplay section, it really stands out from the crowd. Even compared to similar .io and flash games, Planet Panic really stands out and brings new themes to the table(This of course being protecting the planets of a small solar system which grows over time)
Theme - In regards to following the given theme, This being Tiny World, I would say the game follows this quite well. The game requires you to protect a number of small Tiny Worlds at risk of destruction. This is all brought together in a nice and neat package which is fun, intuitive and feels new.
TL:DR - The game is fun, intuitive and engaging. The style and design are perfect for the game and the theme has been followed extremely well.
