A fun, polished metroidvania. Lots of great juicy effects.
The SFX are very good (the cackles as the crab gets its radioactive superpowers, for example). But I found the music to be too repetitive, and I wished for a way to disable just the music after starting the game.
The graphics are maybe a little too busy and soft-focus for the 64x64 resolution. I found it hard to identify hazards while playing. For example, I died by falling in the water because I didn’t see that the water was there.
