The artwork is the major selling point of this. The Pixel Artist did wonders for this production.
However, Theme and Accessibility are major weaknesses of this production. When considering the theme, it feels that there was no influence at all by the theme and that how it might tie in was merely a weak afterthought. In terms of Accessibility, while it is valid to put controls into the Game Page, Manual Reload was not amongst them, so I could only intuit that there were other controls besides these. It was the first thing I looked for when approaching the solution to level 3.
The solution to level 3 was a trick in the control scheme: jump from and pick up the package at close to the same time to get the jump height you need while still being able to pick up the package. From there, apply controls normally. You may consider it valid to have this trick in the game, it should not be a requirement for basic completion. When trying to speedrun a level, though, I'm all for it. Discovering tricks like that is what makes speedrunning fun.
