5 stars: I love the game, the speedrunning concept is really cool for a multiplayer game like this! I'd love an option to hold down to repeatedly jump though, and it would be much nicer if your timer didnt start until you make the first jump. It makes some levels annoying if theres spikes at the start so you can't do a full jump but if you dont hold down while the countdown timer is going off then you'll start late.
5 stars: Amazing game! No ads!! Something I would love is an extra mode: able to race against people on player-made maps! Then there is equally no/little opportunity for racers to practice beforehand. Though there needs to be a separate rating system to filter out non-racing maps like the no moving ones. (And be mindful of hateful or inappropriate messages in maps)
4 stars: Insane Timekiller, No Ads, meaning the experience is 10x better, and smart execution. What i do see as problem is that there are no shortcuts or ways to get WRs quicker / better, meaning that some are just 0.0002s behind yet 2nd or even last place. It is quite hard to earn items, making common items like legendary items at this point. Multiplayer is fine.
4 stars: I think this game has a very interesting concept and is pretty fun, There is a glitch that keeps happening whenever I finish a level where I cannot get back to the main menu, and I have to exit out of the game. The menus seem a bit buggy, but the actual gameplay is really neat. (It was cool watching the dev videos for this...
