Thank you so much for reviewing the game and posting a video of it! It was really interesting seeing your playthrough as the one thing I wish I did more of during the project's development was playtesting.
Yes there are some issues with slope collisions. I didn't think about shooting upwards, that could be a good addition. I'm glad you reached the end. I've received some feedback on maybe extending the timer, as I think it's very difficult to beat first try, which I need to fix.
All in all, glad you enjoyed the game! Thank you also for the constructive feedback :)
