- ZXC was a mistake. (I'm using QWERTZ layout. Please consider rebindable keys)
 - Text crawl too slow. If it's sped up while holding Z, it's not noticable
 - >Tee hee
 - Stuck in the shop. Pressing exit shows the pipboy view, so do buy and sell. Any button on the pipboy leads back to the shop view
 - Knowing to use R to reset would have been useful before I got to the shop
 - >Tee hee
 - Guess S is slide?
 - Lots of empty space in the level design. With the camera this far out, 50% and more of what the player can see is uninteresting scenery they can't enter or otherwise interact with. Why should a player need to see this much nothing?
 - Standard weapon sound getting kinda annoying
 - Climbed ladder in slime room. Camera ain't following me, but the room doesn't change either
 - It's easy to get caught inside one of the floating enemies, leading to a huge health loss for one mistake
 - Getting screen tears in fullscreen mode
 - Room with second canonier enemy doesn't scroll up when moving along the top
 - Redesign your jump. Several times I wanted to use short jumps to get to the right height to shoot an enemy, but couldn't because your jump is static
 - Apparently the canonball is called oilshot
 - Can't go whence I came after acquiring oilshot
 - Splitshot noise needs redesign. Too loud
 - Homing shot tries to get enemies in unreachable places
 - Blind falls are bad design. If a player is supposed to take a long drop they should know whether or not they may take it without taking damage
 - Homing shot does not consistently home in on enemies. Especially visible at second oilshot slime on tubes and after
 - Changing directions sometimes not responsive. Moving in one direction, then immediately switching to the other results in a small delay
 - Floating enemies are hard to kill due to the way jumping works. This could be circumvented by making them move towards player's y position more urgently than to his x position
 - I have yet to find out how to use an energy tank
 - Alt+F4 does not quit the game. Neither does ESC
