Solid information for Game Designers
Format: Paperback, Format: Paperback
Level Up was a great read. It flows well, hits all the important stuff, and it's fun to read explanations from games I've played growing up.
I went to school for Game Art, and Level Up covers everything they taught minus the hands-on experience that the classroom has. Cover to cover of great information.

Typos make this appear sloppy and questionable
Format: Paperback
Number of typos in the first chapter alone makes the info contained within questionable to me. P. 11 Indie games are “mostly releases through streaming services like Twitch and Switch”. Twitch is a streaming video site and Switch is Nintendo’s hybrid handheld/console.
P.13: SHMUP is misspelled as SHUMP
Survival Horror is listed as “players are generally helpless against a supernatural threat” which is not accurate for the genre’s most popular game, Resident Evil, where you’re well-armed against a non-supernatural threat.
Vehicles simulation is listed as a genre but racing is not…even though they are not necessarily the same genre.
P.14 Shigeru Miyamoto’s name is spelled as “Shiguru” I’m sure the following chapters will cover Ye Suzaku and Jean Romato.
