You have a really good base for a rogelike game here. The fact that your power is decreasing over the time played is really interesting and scary.

It is true that there is no much content, but this means you can expand the game in many different directions and reach a very solid result.

11 potions! Cool game dude, solid mechanics, nice gameplay... I felt betrayed when I realized the potions weren't there to help me...

The game has a lot of room for improvement, I guess you know it. I think different enemys would make a good improvement, so then you have to prioritize some enemys instead of others and don't just keep walking in circles and shooting at the mass of enemys.

This game would be amazing with some sound and effects!

As it stands, you don't really feel the impact of your endless onslaught.

Other than that, the game feels really solid and runs without any issues. I just wish there was more to do than to be stuck in a square with endless spawning enemies!
