Very solid experience considering the timeframe. Artstyle has great potential and the creator is obviously very skilled in the department of coding and art design.
Art: 7.5/10 (cool crt effects, custom cursor and pixel art... awesome amount of good and great pixel art considering the time frame)
Music: 6.5/10 (not awesome, but not awful either... of course, one person can't excel at every field instantly... goated menu music tho)
Gameplay: 7/10 (sound effects feel very plesant, and cool way to use the concept "everything has a costcost" through ridiculous objects like a black hole... replayability is fine... not too addictive though... some ui elements feel a bit unpolished, but again, considering the time frame, this is fine... however the user doesn't really get introduced to the goal of the game which could be confusing)
Playability: 10/10 very easy to run, no stutters (lack of complete wide/ultrawide monitor support, which is, again, not an issue for this type of project)
