I couldn't read half of the subtitles because of the white on white background. That's something you should've fixed before uploading, most of your readers missed out on 1/4 of the story. I think the animation was fine, but you really need to work on the timing in the next episode. Really need to have quick timing. The frog bit of him sitting and blinking wasted my time. The frog part where he yells at it and it shows his little "I'm shitting my pants" part took too long as well.
Other than those bits, this was really cool. I could see you doing some excellent work and am looking forward to seeing more.
