Tip Top: Don't Fall! is a fun indie game which acts more as a proof-of-concept than a fully-fledged climbing game. I have not fact-checked this but based on playing the game, it is evident that the devs are climbers themselves or at the very least did their due diligence in researching what goes into lead climbing. While the game isn't very technically impressive, that is not the point as it accurately captures a day out on the crag with its fatigue mechanics and life system. The attention to detail is very pleasing with the chalk-up, clip-in, and movement mechanics overall. To reiterate, this is an excellent example of what a climbing game can be and bodes well for future endeavours that this dev team may embark on. If you are into rock climbing and have a spare hour or two I would 100% recommend giving this game a go.
