Bonk has a lot of ideas, a lot of things to collect for health, brief upgrades (that barely do anything due to how long they last), your head being a weapon so jumping up into enemies damages them and destroys blocks as well as your normal attacks, your headfirst dive attack can be cancelled and started multiple times to get air time or can be used to bounce off enemies, you can bite cliffs to climb them, swim up waterfalls, climb posts, swing up poles, eat fishing line to scale a cliffs you wouldn't be able to climb, find bonus stages, and stages all change up the environment and hazards while usually introducing new mechanics. Really didn't find the game fun to play though despite the things that you could do, didn't really all come together in an interesting way for me, and the controls just never felt responsive.
