Keypad input doesn't work

With the following script

Code (CSharp):

1. using Unity.Entities;
2.  
3. using Unity.Tiny;
4. using Unity.Tiny.Input;
5.  
6. [AlwaysUpdateSystem]
7. public class InputTest : SystemBase
8. {
9.     InputSystem Input;
10.  
11.     void TryKey(KeyCode key)
12.     {
13.         if (Input.GetKeyDown(key))
14.             Debug.Log($"{key} pressed");
15.     }
16.  
17.     protected override void OnUpdate()
18.     {
19.         Input = World.GetExistingSystem<InputSystem>();
20.  
21.         TryKey(KeyCode.LeftArrow);
22.         TryKey(KeyCode.RightArrow);
23.         TryKey(KeyCode.UpArrow);
24.         TryKey(KeyCode.DownArrow);
25.  
26.         TryKey(KeyCode.Keypad0);
27.         TryKey(KeyCode.Keypad1);
28.         TryKey(KeyCode.Keypad2);
29.         TryKey(KeyCode.Keypad3);
30.         TryKey(KeyCode.Keypad4);
31.         TryKey(KeyCode.Keypad5);
32.         TryKey(KeyCode.Keypad6);
33.         TryKey(KeyCode.Keypad7);
34.         TryKey(KeyCode.Keypad8);
35.         TryKey(KeyCode.Keypad9);
36.     }
37. }
38.  

It only prints for arrow keys, numpad/keypad keys don't seem to register at all. This is version 0.31.
