✦ AI summary

Biotoxin: The Dark Days is a budget 2D platformer shooter with an apocalyptic theme that offers a brief experience for players seeking casual entertainment, though it's held back by inconsistent pixel art quality, significant bugs (particularly characters getting stuck on level geometry), sparse audio, and repetitive difficulty spikes. Players are divided on its artistic merit and overall polish, with some finding it an acceptable short diversion while others consider it an unfinished product. Most suggest picking it up only during sales or as a free title rather than at full price.

Overall just another crappy "MyFirstGame.exe." The graphics are bad (there's a difference between minimalist and ♥♥♥♥♥♥ MS Paint work), there don't seem to be a whole lot of sound effects or music, and I quit playing after having to repeat a level multiple times on Easy (twice because my character got stuck in the staircase and I couldn't continue; twice because I ran out of weapons).

It's not a really good game, the gameplay and story are very basic. The pixel art for the game is kinda mediocre and the coding is really buggy. It was not an enjoyable experience. At least It's not expensive

This is a very nice game for if you're bored, are into 2D games, Like apocalyptic storylines, or are fond of platform shooters. The game has a very nice style to it and some pretty good graphics. Had some problems getting stuck on stairs or in doors. but other than that, just about no glitches in the game. Would give it a 6/10

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
