This was actually super fun! The art and mechanics were *chefs kiss*. The only critcism I'd have is what bittyBIGstudio mentioned in their first point too. The margin of error for small guy jumping spikes is so small that I did not think it was an option. I had to read the comments coz I thought lvl 5 was impossible.
That aside, the mechanics are super smooth and the level progression is great. I struggled in lvl 4 (not knowing small guy can jump spikes) but then realized small guy can move independently when big guy is recovering from double jump. Very satisfying and engaging and i like that there's different ways to get thru levels.
