Really fun game! I definitely liked the last level the best, forcing me to not keep the time slowed to make the bullets go away faster, and then getting out asap. This is a really cool mix of mechanics, having a slowdown to avoid bullets when desperate, but possibly being able to refine your speeds to not even need it.
There is a lot of potential here for a nice speedrunning game! With some enhanced level design, that rewards creativity and new thinking, allowing for skips and such, this would be very fun!
Some levels felt like it was forcing a specific path, especially with some lasers that shot too fast to get by, giving the player the sense of "Oh, I can make that if I just go a bit faster" Is key for speedrunning games, which Is why I think the last level was the best, since I was constantly thinking I could Improve on it and get further ahead before needing to stop.
Games like Hot Lava are great examples of this, since doing the level the intended route is normally the slowest. Finding skips throughout the level that require specific speeds and perfect runs are how you get the best times, and are definitely planned by the developers.
Small things like having to press Enter when restarting, instead of being able to use the mouse was a bit tedious, but thats a simple change. Having the timer start once the player moves would also be a nice addition, so I didn't have to press R and then start my run.
Christmas music was a little bit weird, but it worked lol. Overall a great game!
