Charming pixel art and nice music. (Although it was so quiet compared to the sound effects that it took me a while to realize it was there) At the start, the game is ridiculously punishing and enemies feel like bullet sponges, but moving around gets very fun once you get more bullets.
Wish I had known it doesn't have an ending, because I went all the way to floor negative 2...
A few notes:
- I'm almost certain the firepower upgrade doesn't work, it always took the same amount of shots to kill an enemy no matter how many times I had upgraded it
- That room with the 4 pins is vicious, it took me quite a while to start being able to do it without being hit
- Killing a pin while it's flying at you causes its sound effect to loop infinitely until you enter another level with a pin
- 100 floors is a tad ridiculous for the available pool of rooms you can encounter, it got very repetitive
