Awesome fast-paced FPS game! The movement is so smooth. It seems the game hasn't been polished yet, and I'm looking forward to the full version of the game.
(1) There is no indication that I am repairing myself. I can see my energy drop when pressing "R.". But there are no sounds, visuals, or icons telling me that I am actually healing.
(2) There are only three enemy types. It makes ~15 minutes of gameplay too long. Even though I beat all the levels, I got bored after 5 minutes.
But the first 5 minutes of the game is really fun! A great game!
