I really love how polished the retro aesthetic and feel of the game is - not to mention how clever the basic idea is. Small interactions like dashing or pushing your little guys forward are super satisfying, and executing the solution to the levels are challenging but rewarding!
To suggest something that could be improved - since dashing is tied to the arrow keys, when I was moving my character to finely adjust the position of objects I often found myself accidentally dashing and subsequently dying by falling in water or spikes, which was honestly a good laugh but I can imagine people getting pretty frustrated about it and potentially ragequitting the game. Perhaps having a dedicated button for dashing would lead to less input errors and feel more responsive?
Since difficulty seems to be a common complaint, I think making a change like that would help solve the issue without having to compromise on the actual puzzle difficulty, which is actually a big part of the appeal of the game for me.
Congrats on finishing the jam!
