This was kinda neat, having different mini-games for the various kaiju is a cool idea.
The Kaijenny fight was simple but it worked. Well, Kaijenny kept walking towards me after death but ya know, jam issues.
The Kaijoann fight was a bit more involved which was cool, though admittedly I think it needs a better indication of the players progress in the fight. So that's my main suggestion for that battle post-jam.
Overall, its a shame you couldn't finish it. The art's well done and the idea is interesting. The lack of sound is also a shame because that would definitely add some juice to the game.
Congrats on finishing at least part of the game though, good work!
