The text was quite tricky to read in the main menu and the how to play is quite lengthy, having it in the game and shown to the player in readable chunks on start is a good way to have the player know what they doing without having it so hard to read and lengthy.
The enemies spawning outta nowhere was tricky to deal with and got me killed quite quick a lot of the time. The In game UI is great though and a cool idea. Good work overall :)
