The visuals are lacking.
It needs a sprint mechanic.
The mechanics are wonderful—superb. You mentioned that it’s "something to be further developed in the future"—that’s excellent news. I hope there will be levels where a single wrong move ruins everything, where you have to choose between risking the use of an ability right then or finding another way around, and where the impact of one action can bring everything crashing down. This game has a bright future.
