Hey man! I really enjoy your game CTHON. The atmosphere and music still haunts my mind till today when I think about it.
Hmm what I like about the game? I love the music. I love the weapon and enemy design, and I like the pixel graphics. The whole game is wonderfully made overall and it reminds me a little bit of Marathon except if it's lovecraftian and in a Wolf3D-inspired engine.
Now what I don't like about it? Well the Grenadier class is useless as his main weapons runs out of ammo fast. I find myself using the projectile class the most while the melee class's only advantage is his movement speed.
Also I don't like how difficult it is on normal difficulty. I could only complete the game on easy and I have been playing shooters since I was a kid. Enemies are extremely unforgiving and they can chew your health faster than an MG42 spewing out lead. I feel that there should a window for you to evade their attacks.
Lastly, I think it will be great if there is a secret counter for each level so that I don't have to keep backtracking looking for any secret that I have left out
Despite it's flaws, it deserves a cult following and I'd look forward to CTHON 2
