if you added all those restrictions it would definitely be a completely different game, and in my opinion, stand out way less from other entries (and games outside of the jam in general)
that type of game isn't bad, but i feel like there's an overabundance of them, and something where you just get to have fun is very refreshing
in general i feel like when people make games they tend to put in certain mechanics / rules because it's the "standard", but when you think through what each detail would feel like and how it impacts the game you can get a lot more intentional with how you want people to experience your game (all art in general honestly)
everything you put into a game or choose to leave out is a choice you make that will bring the end product closer to what your vision is
that's why i think there's rarely a thing as a "bad game", the game might just not be the experience you were looking for, but it doesn't make it bad game design if you leave out a feature people see as common (punishing your failures for example), it's the opposite even, it's good game design because you took an element, sat with it, and thought okay this doesn't serve my purpose, and that requires a lot more thought
bad game design is one that produces an experience you weren't aiming for, and clearly you nailed showing the experience you wanted
for me it felt really nice to control and physics looked intentional, obviously i don't know what the vision was, but what i ended up experiencing was great
one tiny bug i think i found, was when i was hovering over a platform i was about to click, it got highlighted, but if there was a second platform of the same type in the level it would get highlighted as well
i noticed this on the last level, it could just be how the asset was duplicated or something, not sure how your creation process was, it didn't detract from the game, just thought you might want to look into it if you plan to update later
overall, great job with everything, and i wish you the best of luck on any future project, nice to see you on the jam again :]
