Thank you, it was a really fun evening.
You've got a great balance. The game is moderately difficult, but still fair.
And you've created some exceptionally good bosses. I'd rate the final boss as one of the best ever implemented on EFPSE.
The regular enemies are also very good. They're not very varied, but very well designed. The only thing I'd suggest is making the pig explosion's 3D sprite visually larger to better convey the blast radius.
And the gun looks cool and fires well.
The sound design and the storyline about the effects of trichinosis are also very good.
The only weak point of the game is the level design, although it's not bad. The map quality is a bit lacking in some places. The worst part for me was finding the right path through the ventilation shaft. When you hit another dead end and have to crawl back, it feels like a boring waste of time. A couple of those pig-roaches would have been worth adding for fun. And, of course, the dead ends need to be closer together so you don't have to backtrack too much. But overall, the levels are good, and the platforming elements were surprisingly less frustrating than expected. I really enjoyed it.
Well, while I wait for the second chapter, I'll check out your other games.
