Here is a table for Xotic.
It should support more versions, tested with v1.0.

Options:
Unlimited Health
Unlimited Energy

NOTES:
If ALT+TAB is not working, use CTRL+ESC.
First you need to enable the "Activate Cheats" script, then you can enable the options.

Even if you have Unlimited Health, you can be killed if something is killing you instantly. Doesn't hurt to give some skill points to increase max health.
