Well well. This game is really polished
It has nice graphics, sounds and the Controls are responsive.
But there is alot of glitches and bad design choices
Ill start off with the weird slits that are seen in the next video (When i was playing the camera was stuttering but in the video it is not i might just be crazy)
Second of all is when you jump on the enemy it knocks you away but if you hold the right button (assuming that the enemy is to your right) you will just continuously bounce on the enemy which is really annoying and not fun.
Last problem i have a video off of is the little mehanic where the players "spirit" goes back to the last safe space after hitting a spike (In the video the background is stuttering + i cannot revive so i had to reset the game. Also the little spirit interpolation (LERP) is way too slow)As you addresed in the video some of the enemies and spikes are hard to see and it happend to me on multiple occasions that i jump on some random spikes. A Teal color for the background would look gorgoeus and would not be too distracting (just an reccomendation)
Downward slash as seen in hollow knight would really fit this game + would eliminate the problem of boucing on enemies and dying.
Overall this is a promising games but some design choices are not the best.
