There's an incredibly whimsical and surreal vibe to this, complete with writing that can be fun and oddly verbose at moments. It's a very straightforward narrative, but it's one that keeps you hooked as you play it! It certainly kept my attention. I do also like the small bit of dialogue towards the end that hints at Sven and Stig's lives outside of running into a cave to beat up spiders.
I want to give particular mention to the combat system. I'm always down for an RPG combat system that gets the player really involved with what's happening beyond simply choosing what to do next, and this memory game attack system is a pretty good take on it! I had a maximum of two attacks, yet it never really felt like it because I couldn't be certain what the sequence would be. Like the rest of the game, it's simple, colorful, a little strange & surreal, and had a very tight grip on my attention.
Nice work overall!
