Job well done! At the request of the developer, what needs to be improved:
1) The character’s speed is too high, the game as a whole is rhythmic, but it seems that it is better to reduce the speed a little, both for the character and for the enemies.
2) Jump towards the mouse pointer, I think it’s better to change it and jump towards the direction of the character’s movement, I think it will be more convenient.
3) More action! The game is too difficult because the reload time is too long.
4) Why take away mana for jumping? It seems to me better to take away mana for using special weapons (all staves), and not give the player the opportunity to use them immediately from the beginning of the game, but hide them in chests or something like that. I've been using a red staff since the beginning of the game and I don't need another weapon because I think the red staff is the most effective.
5) The sounds in the game need to be made louder and the background music quieter.
6) And lastly, of course the game is a roguelike, but you took it too seriously)) starting the game from the beginning is not very fun after completing several levels.
In general, this is all I saw during the game, I like the music in the game, the graphics, the atmosphere. I wish you not to abandon the project, develop it and make it even more interesting and better!
